feat(sqlite): enhance migration system and database initialization

- Add robust logging and error tracking to migration system
- Implement idempotent migrations with transaction safety
- Add detailed progress tracking and state verification
- Improve error handling with recoverable/non-recoverable states
- Add migration version validation and sequential checks
- Implement proper rollback handling with error recording
- Add table state verification and debugging
- Fix migration SQL parsing and parameter handling
- Add connection pool management and retry logic
- Add proper transaction isolation and state tracking

The migration system now provides:
- Atomic transactions per migration
- Automatic rollback on failure
- Detailed error logging and context
- State verification before/after operations
- Proper connection management
- Idempotent operations for safety

This commit improves database reliability and makes debugging
easier while maintaining proper process isolation. The changes
are focused on the migration system and do not require
restructuring the existing ElectronPlatformService architecture.

Technical details:
- Added MigrationError interface for better error tracking
- Added logMigrationProgress helper for consistent logging
- Added debugTableState for verification
- Added executeWithRetry for connection resilience
- Added validateMigrationVersions for safety
- Enhanced SQL parsing with better error handling
- Added proper transaction state management
- Added connection pool with retry logic
- Added detailed logging throughout migration process

Note: This commit addresses the database initialization issues
while maintaining the current architecture. Further improvements
to the ElectronPlatformService initialization will be handled
in a separate commit to maintain clear separation of concerns.
