docs: Antigravity technical reference — REST API, model IDs, auth, debugging

- Full reasoning round-trip: capture reasoning_content + tool_calls from
  stream, store by tool_call_id, reinsert before next codebuff POST
- Primary path no longer disables thinking (codebuff doesn't forward the flag)
- Fallback retry uses DeepSeek native {thinking:{type:'disabled'}} format
- Replaced broken _fb_retry_no_reasoning + _fb_retry_stripped with
  single _fb_retry_thinking_disabled
- New _ds_store_assistant(), _ds_rebuild_tool_history() functions
- oa_stream_to_sse() now captures tool_calls in reasoning_out dict
- Multi-turn Codex CLI sessions with function calls now complete successfully
