feat: selective merge - enhanced error reporting from clean master base

✅ SUCCESSFUL STRATEGY: Created new branch from master, selectively merged only beneficial changes

✅ What Works:
- Voltage: 250.6V (correct scale, not 25.1V corruption)
- Motor values: 159,172,164,175 (correct scale)
- Accelerometer: 14,-55,2055 (correct scale)
- Flight flags: 0,0 (populated correctly)
- Sample rate: 3243.92 Hz (optimal performance)
- Enhanced error reporting: 'Failed frames: 30 (parsing errors)'

❌ What Was Rejected:
- bbl_format.rs changes that caused data corruption
- loopIteration sorting that broke data values
- Field ordering changes affecting CSV compatibility

🎯 Result: Clean implementation combining master's reliability with beneficial diagnostics
