v1.4.4 - Fix Things 3 freezes from SQLite lock contention

Fixed

• Upgraded things.py to v1.0.0 to fix SQLite lock contention with Things 3
  • things.py 0.x held open SQLite connections via the things3 module, blocking Things 3's WAL commits during cloud sync
  • things.py 1.0.0 uses read-only connections with proper cleanup via weakref.finalize()
  • Resolves intermittent Things 3 UI freezes caused by btreeInvokeBusyHandler blocking on sync commits
