refactor: enhance SQLite error handling and type safety 

Current State:
- SQLite initialization completes successfully
- API exposure and IPC bridge working correctly
- Type definitions and interfaces properly implemented
- Enhanced error handling with specific error codes
- Comprehensive logging system in place

Critical Issue Identified:
SQLite initialization timeout causing cascading failures:
- Components attempting database operations before initialization complete
- Error logging failing due to database unavailability
- Multiple components affected (HomeView, AccountView, ImageMethodDialog)
- User experience impacted with cache clear prompts

Changes Made:
- Added proper TypeScript interfaces for SQLite operations
- Enhanced SQLiteError class with error codes and context
- Implemented input validation utilities
- Added detailed logging with timestamps
- Improved error categorization and handling
- Added result structure validation

Type Definitions Added:
- SQLiteConnectionOptions
- SQLiteQueryOptions
- SQLiteExecuteOptions
- SQLiteResult
- SQLiteEchoResult

Error Codes Implemented:
- SQLITE_BUSY
- SQLITE_NO_TABLE
- SQLITE_SYNTAX_ERROR
- SQLITE_PLUGIN_UNAVAILABLE
- SQLITE_INVALID_OPTIONS
- SQLITE_MIGRATION_FAILED
- SQLITE_INVALID_RESULT
- SQLITE_ECHO_MISMATCH

Next Steps:
1. Implement initialization synchronization
2. Add component loading states
3. Improve error recovery mechanisms
4. Add proper error boundaries
5. Implement fallback UI states

Affected Files:
- electron/src/rt/sqlite-init.ts
- src/types/electron.d.ts

Note: This is a transitional commit. While the structure and type safety
are improved, the initialization timeout issue needs to be addressed in
the next commit to prevent cascading failures.

Testing Required:
- SQLite initialization timing
- Component loading sequences
- Error recovery scenarios
- Database operation retries
