Fix infinite loop in file picker with proper initialization flag

- Use isInitialized flag to prevent effect re-triggering
- Use gitFilesFetched flag to prevent duplicate git API calls
- Fetch git files and initial files only once on first open
- Only refetch when search query actually changes
- Git files are optional - don't block on empty results
- Logs show initialization state for debugging
