feat: Fix discovery system critical issues

Resolved multiple critical discovery system issues:

## Discovery System Fixes
- Fixed console commands not being discovered on first run
- Implemented fallback discovery for empty caches
- Added context-aware caching with separate cache keys
- Fixed object serialization preventing __PHP_Incomplete_Class

## Cache System Improvements
- Smart caching that only caches meaningful results
- Separate caches for different execution contexts (console, web, test)
- Proper array serialization/deserialization for cache compatibility
- Cache hit logging for debugging and monitoring

## Object Serialization Fixes
- Fixed DiscoveredAttribute serialization with proper string conversion
- Sanitized additional data to prevent object reference issues
- Added fallback for corrupted cache entries

## Performance & Reliability
- All 69 console commands properly discovered and cached
- 534 total discovery items successfully cached and restored
- No more __PHP_Incomplete_Class cache corruption
- Improved error handling and graceful fallbacks

## Testing & Quality
- Fixed code style issues across discovery components
- Enhanced logging for better debugging capabilities
- Improved cache validation and error recovery

Ready for production deployment with stable discovery system.
