chore(release): prep v0.8.51 — Arcee provider, cycle removal, UI fixes
Release-preparation checkpoint for v0.8.51 (workspace + npm bumped to 0.8.51).
Added:
- Arcee AI direct provider: [providers.arcee], ARCEE_API_KEY/BASE_URL/MODEL,
CLI auth, provider + model picker, registry. Default direct-API model is
trinity-large-thinking (reasoning, 262K ctx/out); preview + mini selectable.
Cloudflare-WAF-safe opening turn (benign read-only tool surface, system-prompt
payload splitting) and reasoning_content replay on tool-call turns.
- Expanded model catalog (qwen3.6 flash/plus/max-preview, Xiaomi MiMo v2.5
chat/ASR/TTS); provider-aware model picker with per-provider saved models.
Changed:
- Auto-compaction is percentage- and model-aware
(compaction_threshold_for_model_at_percent; default 80%; auto-enable for
<=256K windows, opt-in for 1M models).
- Provider/gateway HTTP errors sanitized (HTML/WAF interstitials collapsed,
401/403 split into authentication vs authorization).
Removed:
- The session cycle / checkpoint-restart system: /cycles, /cycle, /recall,
recall_archive tool, cycle_manager, cycle-handoff prompt, sidebar cycle lines,
EngineConfig.cycle / Event::CycleAdvanced / seam cycle thresholds.
Fixed:
- Orphaned assistant 'blue dot' role glyph on whitespace-only turns.
- Sidebar mouse-wheel scroll leaking into the transcript.
- Sidebar hover tooltip overlap + warning-orange styling.
- README Constitution description corrected to match prompts/base.md.
- Repaired release-blocking unit/integration tests after the refactors.
Preflight: cargo fmt clean, workspace builds, 3903 tui tests pass (1 known
flaky MCP SSE test under parallel load, passes in isolation).
