Adds first-class DeepSeek V4 Pro and Flash support, updates the default model to deepseek-v4-pro, aligns legacy aliases with the current V4 1M context behavior, and fixes thinking-mode request handling.
Key fixes:
- Send DeepSeek's raw Chat Completions `thinking` parameter at the top level instead of SDK-only `extra_body`.
- Preserve assistant `reasoning_content` for all prior thinking-mode tool-call turns so subsequent requests satisfy DeepSeek V4's replay requirement.
- Fix npm wrapper concurrent first-run downloads by using per-process temporary download paths.
- Add `.mailmap` so historical bot-attributed commits aggregate under Hunter Bown where mailmap is honored.
Verified with the full local Rust gate, live DeepSeek V4 smoke, npm wrapper temp-install smoke, and green PR CI across Linux, macOS, and Windows.
Add Yahoo Finance quote tool with chart fallback, redesign header widget
with proportional truncation and context bar, refactor footer status strip,
expand test suite to 680+ tests, and fix blocking issues (usize underflow
in header, tempdir leak in finance tests, per-call HTTP client creation).
Keep legacy /normal and settings fallback behavior mapped to Agent, align docs around the three visible modes, and include the current TUI and onboarding refinements in this worktree.
