7034e910c4 fix: generate Mistral-compatible 9-char alphanumeric tool call IDs (#1242)
* fix: generate Mistral-compatible 9-char alphanumeric tool call IDs

Mistral's API requires tool call IDs to match [a-zA-Z0-9]{9} exactly.
Previously, IDs like 'turn1_0', 'recovered_0', 'call_<uuid>', and
'generated_tool_call_N' were generated, which Mistral rejects with
HTTP 400.

Add generate_tool_call_id() that produces deterministic 9-char base-36
IDs from two seed values, and use it at all tool call ID generation
sites.

Fixes #1241

* Update src/llm/provider.rs

* fix: address review feedback on Mistral tool-call ID generation

- Remove .unwrap() in generate_tool_call_id (provider.rs) per zero-tolerance policy
- Remove .expect() in normalized_tool_call_id (rig_adapter.rs), use direct array indexing
- Replace magic constant 99 with named RECOVERED_TOOL_CALL_SEED in reasoning.rs
- Add tests for normalized_tool_call_id: passthrough, hashing, empty/whitespace, determinism
- Add comment explaining intentional use of turn_idx vs turn.turn_number in session.rs
- Fix duplicate `mod tests` block in provider.rs (pre-existing compile error)
- Update stale test assertions expecting old `generated_tool_call_` prefix format
