Michael Chus	3d222b7f14	feat: add ConnectionManager for lazy database connections ... Introduced ConnectionManager to support offline-first architecture: - New internal/db/connection.go with thread-safe connection management - Lazy connection establishment (5s timeout, 10s cooldown) - Automatic ping caching (30s interval) to avoid excessive checks - Updated middleware/offline.go to use ConnectionManager.IsOnline() - Updated sync/worker.go to use ConnectionManager instead of direct DB This enables the application to start without MariaDB and gracefully handle offline/online transitions. Part of Phase 2.5: Full Offline Mode Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>	2026-02-02 23:29:04 +03:00
Michael Chus	143d217397	Add Phase 2: Local SQLite database with sync functionality ... Implements complete offline-first architecture with SQLite caching and MariaDB synchronization.
