- Add getAppVersion() utility that walks up directories to find package.json - Add parseSemver() for semver string parsing with major/minor/patch components - Add CentralCore version sync methods (getAppVersion, syncVersion, getLastSyncTime, getSyncStatus) - Add CentralCore events for version sync lifecycle (version-sync-started, version-sync-completed, version-sync-failed) - Add schema v4 migration with appVersion and lastSyncTime columns to projects table - Export new types (CentralSyncStatus, SyncResult) and utilities via @fusion/core - Update memory.md documentation with new types - Fix TypeScript error in app-version.ts (return pkg.version directly instead of cached variable)
