# Fix critical stability issues and add comprehensive retry mechanisms

## Major Fixes
- **Fix infinite loop crashes**: Remove recursive calls in check_stuff() that caused Home Assistant crashes
- **Fix duplicate setup errors**: Prevent "Config entry has already been setup" errors with proper region checking
- **Fix API instance conflicts**: Use single NordpoolData instance to prevent resource conflicts

## New Features
- **Comprehensive retry mechanisms**: Multi-layer retry system for API calls with exponential backoff
- **Recorder attribute exclusion**: Prevent large attributes from bloating database while keeping them accessible
- **Enhanced error handling**: Safe API call wrappers with detailed logging and graceful degradation

## Performance Improvements
- **Database optimization**: Exclude raw_today, raw_tomorrow, and other large arrays from recorder
- **HTTP timeout configuration**: 30-second total timeout, 10-second connect timeout for better reliability
- **Memory efficiency**: Reduced database size and query overhead

## Technical Details
- Add @backoff decorators to _io() and fetch() methods in aio_price.py
- Implement _safe_api_call() wrapper in data.py with comprehensive exception handling
- Use _unrecorded_attributes class attribute for proper recorder exclusion
- Add duplicate region setup prevention in __init__.py
- Enhanced exception coverage: ClientError, ClientTimeout, TimeoutError, ConnectionError, KeyError, ValueError, TypeError

## Breaking Changes
None - All changes are backward compatible
