- open_store_readonly(): stat() PermissionError (non-group user on the
2750 store dir) now maps to StoreFault so status/TUI degrade instead
of crashing with a traceback.
- init_store(): chmod db + -wal/-shm group rw after WAL setup — SQLite
WAL readers need write access to sidecars even for mode=ro opens.
- Store dir 2750 → 2770 (tmpfiles + make install) and UMask=002 on the
collect unit so root-created files stay group-accessible.
- rpm %post upgrade path re-runs systemd-tmpfiles --create to correct
placement modes on existing machines.
Bump to 0.3.3.
