feat: add persistent lifetime stats and sync achievements

- Add lifetime stats persistence to Rust backend
- Sync achievement state between frontend and backend on startup
- Add commands for loading/saving stats to disk
- Expand achievement definitions with 150+ new achievements
- Fix stats store to properly track total vs session metrics
