- Added Error() and Fatal() logging functions for non-debug errors - Added Panic() function to log panics with full stack traces - Added RecoverPanic() for defer statements to catch crashes - Added panic recovery to main() function - Added panic recovery to queue job processing goroutine - All panics now logged to videotools.log with timestamps and stack traces - Helps diagnose UI crashes that occur during FFmpeg processing 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
