fix: restore migration 014, bump version to 0.2.50, harden pr-review workflow

- Restore 014_create_ai_providers migration and tests missing due to
  branch diverging from master before PR #34 merged
- Bump version from 0.2.10 to 0.2.50 to match master and avoid regression
- Trim diff input to 20 KB to prevent Ollama token overflow
- Add --max-time 120 to curl to prevent workflow hanging indefinitely
