refactor: remove markdown docs and revert unnecessary Sentry disabling

- Remove PR_DESCRIPTION.md (will be added manually to PR)
- Revert LOCAL_DEVELOPMENT.md changes
- Restore original Sentry Flask integration in main.py (no interference with WorkflowTracer)
- Restore original github_sdk.py send_trace method (GithubClient not used in current implementation)
