Subject: [PATCH] Add comprehensive test that proves console: false disables
 error reporting

- Test directly posts to /_bun/report_error endpoint to verify functionality
- First test: Error IS printed with default configuration
- Second test: Error is NOT printed with console: false
- Both tests pass, proving the implementation works correctly
- Removed debug logging from production code
