Introduce a shared enum-based system for categorizing message types
across the Rust backend and JavaScript frontend. This replaces magic
numbers with named constants for improved type safety, readability, and
maintainability.
The implementation includes:
- Rust MessageType enum with serialization support
- JavaScript constants matching the Rust enum values
- Helper
This commit replaces all hardcoded message type integers (0, 1, 2, 3, 4,
5) with named constants from a new MessageType module, improving code
readability and maintainability across the codebase.
- Database migrations run automatically on startup
- New QUICK_START.md with usage examples and troubleshooting
- Better handling of already-running services
