* upgrade Claude to Opus 4.6 with --effort max for --max mode

- mini: haiku → sonnet
- auto: opusplan → opus (Opus 4.6)

* update action lockfile for claude-agent-sdk 0.2.39

Co-authored-by: Cursor <cursoragent@cursor.com>

* add tool_use_summary handler for SDK 0.2.39

Co-authored-by: Cursor <cursoragent@cursor.com>

* integrate gpt-5.3-codex with runtime model availability detection

checks GET /v1/models at agent start to determine if gpt-5.3-codex is
available for the API key, falling back to gpt-5.2-codex when it isn't.
model resolution runs concurrently with CLI install for zero added latency.
also bumps @openai/codex-sdk from 0.80.0 to 0.98.0.
