feat: integrate TinyHumans memory client for skill data synchronization

- Added `syncMemoryClientToken` utility to synchronize JWT token with the TinyHumans memory client after user login and Redux rehydration.
- Updated `PersistGate` in `App.tsx` to call `syncMemoryClientToken` on lift.
- Modified `SkillManagementPanel` to use `triggerSync` for skill management instead of stopping and starting skills.
- Implemented memory commands in Tauri for initializing and querying the TinyHumans memory client.
- Enhanced skill instance handling to persist sync data and clear memory on OAuth revocation.
- Introduced a new memory module to manage skill data synchronization effectively.
