feat(v0.8.44): SWE-bench adapter, markdown table fix, contributor sync, receipt truncation fix

- SWE-bench: codewhale swebench run/export writes prediction JSONL
  from working-tree diff, with untracked-file inclusion via git add -N
- CLI: --workspace / -C global flag forwards to TUI for file ops
- CLI: codewhale exec --auto semantics clarified in help text
- Markdown: table pipes inside inline code no longer create phantom columns
  (split_table_cells with backtick-awareness)
- Receipt: floor_char_boundary prevents multibyte UTF-8 slice panic
- Contributors: Ling (LING71671 #1839 #1911), Ben Younes (ousamabenyounes #1938),
  jeoor npm fix (#1860) credited across all 3 READMEs
- ja-JP README: 19 contributors synced to parity with EN/zh-CN (80 each)
- Docs: SWEBENCH.md, RECURSIVE_SELF_IMPROVEMENT.md, MODES.md exec clarification
- Sub-agent footer: Alt+V hint now says 'details' not 'raw'

+## Agent-Assisted Improvements
+
+CodeWhale is allowed to help improve CodeWhale, but the contribution still has
+to be shaped for human review. The recommended workflow is the
+[recursive self-improvement prompt](docs/RECURSIVE_SELF_IMPROVEMENT.md): run it
+from a fresh fork or branch, let the agent find exactly one small friction point,
+and stop after one patch. DeepSeek V4 Pro is the first-class path for this loop
+today, but the review shape matters more than the provider.
+
+The useful output is not "ideas for improvement." The useful output is a
+specific reproduction, a minimal diff, focused checks, and a PR description that
+explains the trade-off. Do not use an agent to touch auth, credentials, sandbox
+policy, publishing/release plumbing, provider policy, telemetry, sponsorship,
+branding, or global prompts without prior maintainer sign-off.

@@ -1,56 +0,0 @@
-## Mode: Goal
-
-You are running in Goal mode — persistent objective achievement.
-
-Goal mode is the determined mode. When a goal is set, you work toward it across
-turns until the objective is achieved, blocked by an unresolvable obstacle, or
-explicitly stopped by the user. You do not wait for the next prompt. You do not
-declare partial progress and stop. You continue.
-
-Your tools are the same as Agent mode — full read, write, shell, sub-agent,
-and code execution access, gated by the active approval policy. Use every
-available capability to advance the objective.
-
-### Goal Loop
-
-After every completed turn, evaluate:
-
-1. **Is the objective achieved?** Check tests, build, changed files, docs,
-   install state, release gates, and user acceptance criteria. Cite specific
-   evidence — a passing test, a committed file, a verified build.
-
-2. **If not achieved:** Identify the single highest-leverage next action.
-   Execute it immediately. Do not pause. Do not ask for permission to
-   continue within the goal loop. The user set the goal; your job is to
-   reach it.
-
-3. **If blocked:** State what blocks progress, what you tried, and what
-   would unblock it. Wait for the user. Do not loop on the same obstacle.
-
-4. **If achieved:** Declare completion with evidence. Summarize what was
-   done, what evidence proves it, and what remains for the user to verify.
-
-### Wakeup Check
-
-At the start of each turn, before acting on the user's message, briefly
-verify whether the goal is already satisfied by the current state of the
-workspace. A passing test suite, a clean build, a deployed artifact — any
-of these may indicate the goal was achieved by a previous session and the
-user just hasn't noticed yet. If so, report it.
-
-### Token Budget
-
-If a token budget was set (`/goal "objective" budget: 50000`), track
-consumption. When approaching the budget, prioritize the highest-leverage
-remaining action. If the budget is exhausted before completion, report
-progress and remaining work — do not silently stop.
-
-### Relationship to Other Modes
-
-Goal mode is orthogonal to execution modes. The approval policy (suggest /
-auto / never) governs which actions require confirmation. The goal governs
-what you are trying to achieve. Both apply simultaneously.
-
-Use `checklist_write` for granular progress tracking. Use `update_plan`
-when the approach changes materially. Each completed checklist item is
-evidence of progress toward the goal.

+# Model Lab Roadmap
+
+Model Lab is the planned open-model workbench for CodeWhale. The north star is
+simple: CodeWhale should become the best terminal coding agent for open-source
+and open-weight models across every provider that offers them. Model Lab is how
+those models become discoverable, evaluable, routable, servable, and exportable
+without weakening the current terminal-agent contract: local workspace control,
+explicit provider auth, approval gates, and clear privacy boundaries.
+
+This document is roadmap language. It does not mean every workset below is
+implemented today.
+
+## Implemented Today
+
+- DeepSeek is the first-class default provider today, with `deepseek-v4-pro`,
+  `deepseek-v4-flash`, streaming thinking blocks, Fin routing, `DEEPSEEK_*`
+  environment variables, and `~/.deepseek` config compatibility.
+- OpenRouter, Novita, Fireworks, NVIDIA NIM, AtlasCloud, Wanjie Ark, generic
+  OpenAI-compatible endpoints, SGLang, vLLM, and Ollama are supported provider
+  paths where their IDs appear in `/provider`, `codewhale --provider`, or
+  `codewhale models`.
+- Model auto-routing chooses a concrete DeepSeek model and thinking level per
+  turn. It is not a TUI mode.
+- Fin is the fast `deepseek-v4-flash` thinking-off path for routing,
+  summaries, cheap checks, RLM child calls, wakeup verification, and
+  binary-completion checks.
+- Self-hosted OpenAI-compatible endpoints can be used through SGLang, vLLM,
+  Ollama, or the generic `openai` provider configuration.
+
+## Not Implemented Yet
+
+- A native Hugging Face provider or Hub browser.
+- Built-in Hugging Face model card, dataset, adapter, safetensors, or Jobs
+  workflows.
+- Native Unsloth, NeMo, or Arcee integrations.
+- A dedicated Model Lab UI tab.
+- Built-in benchmark suites, eval leaderboards, hosted observability, or
+  training-infrastructure orchestration.
+
+Until those land, use the provider paths above, MCP servers, or external
+workflows explicitly configured by the user.
+
+## Model Lab Principle
+
+Model Lab should help users answer practical questions:
+
+- Which model should handle this turn?
+- Which open or open-weight model can I run locally or through a trusted
+  provider?
+- Which provider offers this model with the latency, price, context window,
+  license, and privacy posture I need?
+- What did this model cost, how did it perform, and what data left my machine?
+- Can I reproduce, export, or self-host the route?
+
+It should never hide provider boundaries, silently upload local artifacts, or
+describe a model as available before CodeWhale can actually route to it.
+
+## Hugging Face Workset
+
+Planned scope:
+
+- Hub API auth and model discovery.
+- Model cards, licenses, tags, safetensors metadata, adapters, and dataset
+  links surfaced in a terminal-friendly way.
+- Inference Providers as explicit provider choices when the user configures
+  them.
+- Hugging Face Jobs as an optional remote execution path for user-approved
+  experiments.
+
+Non-goal for now: claiming a native Hugging Face provider exists before it is
+implemented in code.
+
+## Unsloth Workset
+
+Planned scope:
+
+- Fine-tuning recipes and adapter workflows for users who already own the data
+  and compute path.
+- Export guidance that keeps dataset, adapter, and checkpoint locations explicit.
+- Compatibility notes for models that can return to local serving or a hosted
+  OpenAI-compatible endpoint.
+
+## NeMo Workset
+
+Planned scope:
+
+- Training and alignment workflow notes for users operating NVIDIA-centric
+  infrastructure.
+- Clear boundaries between NVIDIA NIM inference support that exists today and
+  future NeMo training or customization workflows.
+
+## Arcee Workset
+
+Planned scope:
+
+- Small-model routing and specialization experiments.
+- Exportable routes that make it clear when a task is handled by a smaller
+  model, Fin, or full DeepSeek reasoning.
+
+## Serving Workset
+
+Planned scope:
+
+- Better local and private serving ergonomics for SGLang, vLLM, Ollama, and
+  OpenAI-compatible gateways.
+- Health checks, model listing, context-window metadata, and route validation.
+- No silent network exposure: public endpoints must be configured explicitly.
+
+## Eval Workset
+
+Planned scope:
+
+- Reproducible task suites for coding, review, docs, release checks, and
+  long-context workflows.
+- Side-by-side route comparisons where the exact model, provider, thinking
+  level, prompt, and tool policy are captured.
+
+## Observability Workset
+
+Planned scope:
+
+- Local-first traces for turn routing, tool calls, approvals, cost, cache
+  behavior, and context pressure.
+- Export rules that redact secrets and require explicit user action before data
+  leaves the machine.
+
+## Training Infra Workset
+
+Planned scope:
+
+- Recipes for dataset preparation, adapter training, artifact naming, and
+  promotion into serving.
+- Separation between local/private artifacts and anything published to a hub or
+  registry.
+
+## Privacy And Export Rules
+
+- Local files, prompts, transcripts, traces, model outputs, eval results,
+  adapters, datasets, and checkpoints should remain local unless the user
+  explicitly chooses a provider or export destination.
+- Provider auth must remain explicit. `DEEPSEEK_*`, OpenRouter, Hugging Face,
+  and self-hosted credentials should not be inferred from unrelated config.
+- Exportable artifacts should include provenance: source model, provider,
+  route, tool policy, eval inputs, and redaction status.
+- Public sharing, hosted telemetry, sponsorship badges, and external branding
+  require maintainer approval.

+# Recursive self-improvement prompt
+
+CodeWhale is built for open-source and open-weight coding models. DeepSeek V4
+Pro is the first-class path today because its cache economics make long agent
+loops practical, but the contribution shape should remain portable to other
+open/open-weight paths as they mature. One practical way to help is to let
+CodeWhale inspect itself and return a small, reviewable improvement.
+
+This is the "100-to-1 model": one clear prompt, many cheap agent-hours, one
+artifact a maintainer can review. It is not a benchmark and not permission to
+rewrite the project. It is a contribution shape.
+
+> [!Tip]
+> The **100-to-1 model** is a nod to Ralph Bown's 1948 public demonstration of
+> the transistor. The device itself was tiny; the large model made the structure
+> easy to inspect. CodeWhale uses the metaphor in the same practical sense: the
+> agent may do a lot of cached, tool-using, sub-agent work, but the contribution
+> should arrive as one visible artifact a maintainer can review.

+You are running inside CodeWhale on DeepSeek V4 Pro.
+
+Your task is to improve CodeWhale itself by finding exactly one small,
+reviewable place where the harness, docs, tests, or contributor workflow causes
+friction.
+
+Goal:
+- Convert agent attention into a maintainer-reviewable contribution.
+- Prefer bug fixes, regression tests, clearer docs, sharper error messages, or
+  one narrow contributor-experience improvement.
+- Do not propose new product direction, provider policy, telemetry,
+  sponsorship, branding, auth, sandbox, publishing, release, or global prompt
+  changes unless the maintainer has already asked for that exact scope.
+
+Working rules:
+1. Inspect the repo and current open issues before editing.
+2. Choose one issue, TODO, failing test, docs ambiguity, confusing error, or
+   repeated papercut.
+3. State the exact target and why it is small enough to review.
+4. Reproduce the problem when possible. If it is docs-only, quote the confusing
+   sentence and the reader impact.
+5. Make the minimum patch.
+6. Run the smallest relevant checks first; broaden only if the touched surface
+   warrants it.
+7. Stop after one patch. Do not keep looking for more improvements.
+
+Output:
+- Summary of the issue found.
+- Files changed.
+- Tests or checks run, with results.
+- Any risk or follow-up the maintainer should know.
+- Suggested PR title.

+# SWE-bench
+
+CodeWhale's SWE-bench adapter writes the prediction file that the official
+SWE-bench evaluation harness expects. It does not replace the harness; it
+generates `model_patch` rows from a local task workspace.
+
+## One Instance
+
+Start from a workspace checked out at the SWE-bench instance base commit, with
+the issue text saved locally:
+
+```bash
+codewhale swebench run \
+  --instance-id django__django-12345 \
+  --issue-file issue.md \
+  --predictions-path all_preds.jsonl
+```
+
+`run` invokes tool-backed non-interactive mode, equivalent to
+`codewhale exec --auto`, with `stream-json` output by default. When the turn
+finishes, CodeWhale exports `git diff --binary --no-ext-diff` as one JSONL
+prediction row:
+
+```json
+{"instance_id":"django__django-12345","model_name_or_path":"codewhale/deepseek-v4-pro","model_patch":"diff --git ..."}
+```
+
+If you already ran CodeWhale, or edited the workspace manually, export the
+current diff without another model turn:
+
+```bash
+codewhale swebench export \
+  --instance-id django__django-12345 \
+  --predictions-path all_preds.jsonl
+```
+
+Both commands update the row for the same `instance_id` instead of appending a
+duplicate row. Untracked files are marked with `git add -N` before diff export
+so newly-created files appear in the patch.
+
+## Evaluate
+
+Install SWE-bench and Docker using the official SWE-bench setup instructions,
+then pass the prediction file to the official harness:
+
+```bash
+python -m swebench.harness.run_evaluation \
+  --dataset_name princeton-nlp/SWE-bench_Lite \
+  --predictions_path all_preds.jsonl \
+  --max_workers 1 \
+  --run_id codewhale-smoke
+```
+
+On Apple Silicon, the official SWE-bench docs recommend adding
+`--namespace ''` so images build locally instead of pulling Linux images.
+
+## Batch Driver Shape
+
+A simple batch runner should prepare each instance workspace, write the issue
+body to `issue.md`, run `codewhale swebench run`, then call the harness once
+on the accumulated `all_preds.jsonl`.
+
+For reproducible runs, pin:
+
+- CodeWhale version and commit: `codewhale --version`
+- Model label: `--model-name-or-path codewhale/deepseek-v4-pro`
+- Dataset and split used by the harness
+- Docker platform and worker count
+- The `all_preds.jsonl` file and CodeWhale stream logs
