Move database ownership, blocking IO and TQL binding into tt-adapter-triviumdb
and upgrade the native engine to 0.8.8. Preserve the plugin API capabilities
with awaited open, numeric IDs and explicit shared-namespace lifecycle.
Coordinate archive IO with database maintenance and restore each namespace
as a complete file group. Keep behavior tests for persistence, parameter
binding, transactions and recovery instead of per-method forwarding tests.
Validated with pnpm run check and tauri-pilot against the macOS app using
the real data root; temporary test namespaces were removed afterward.
