feat(open-sse): add schema coercion and tool sanitization

- introduce open-sse/translator/helpers/schemaCoercion.ts to coerce

  pipeline; ensure tool descriptions are sanitized
- inject empty reasoning content for tool calls when target is OpenAI
  format
- update qwen base URL to DashScope-compatible endpoint
- extend antigravity static catalog with Gemini 3.1 pro preview models and
  update Gemini model specs with preview aliases
- implement call log max cap caching with TTL; expose invalidateCallLogsMaxCache
  and invalidate on settings PATCH
- add tests: call-log-cap.test.mjs and tool-request-sanitization.test.mjs;
  extend tests for Windsurf integration and gemini previews
- update CLI runtime and tools to include Windsurf as a guide-only tool
- add maxCallLogs to validation schemas (settings and updateSettings)
