ForeverCodex

## ForeverCodex v1.0.23

### Performance
- Greatly reduced CPU usage during login and relog.
- Removed expensive full RecipeIndex rebuilds from the login path.
- Removed unnecessary full database normalization during every addon startup.
- Reduced repeated profession scans triggered during login.
- Reduced expensive recipe/category lookups during synchronization.

### Sync
- Added a lightweight automatic revision handshake after login.
- Missing or outdated profession data is now requested only when needed.
- Login sync now selects a single suitable peer instead of requesting the same data from multiple guild members.
- Cached recipe data from offline crafters can still be relayed through other ForeverCodex users.
- No full recipe database rebuild is performed in the background while the Codex is closed.
- Manual full synchronization remains available through the Sync tab or /fc sync.

### Changed
- Profession and recipe changes are still announced automatically when detected.
- Recipe materials continue to load on demand instead of being preloaded.
