docs: fix config defaults and stale references in CLAUDE.md

- temperature: 0.7 → 0.3 (matches actual default)
- timeout_secs: 30 → 300 (matches actual default)
- DISCUSSION_HUNK_LEVEL_SPLITTING.md → GitHub Discussion #2
- Add missing test files: languages, history, template

 ### Known Issues
 
-- **Non-atomic split commits**: The split flow uses `unstage_all → stage_files → commit` per group with no rollback. If an intermediate commit fails, earlier commits remain. Documented via TOCTOU comment in `app.rs`. Future improvement: index snapshot with full rollback (see `DISCUSSION_HUNK_LEVEL_SPLITTING.md`).

 - **No streaming during split generation**: When commit splitting generates per-group messages, LLM output is not streamed to the terminal (tokens are consumed silently). Single-commit generation streams normally. Low priority — split generation is fast since each sub-prompt is smaller.
 - **Thinking model output**: Models with thinking enabled prepend `<think>...</think>` blocks before their JSON response. The sanitizer strips both `<think>` and `<thought>` blocks (closed and unclosed) during parsing. The `think` config option (default: `false`) controls whether Ollama's thinking separation is used. The default model `qwen3.5:4b` does not use thinking mode and works well with the default `num_predict: 256`.
 - **No think-then-compress**: Explicit `<thought>` prompting is not used — small models (<10B) exhaust their token budget on analysis instead of JSON output. The pre-computed EVIDENCE/CONSTRAINTS/SYMBOLS sections serve this role. Revisit for 70B+/cloud APIs.
