Wires the isolated runtime into TREK. Admins can now activate a plugin from the
panel and its HTTP routes work end to end, still behind the kill switch.
- PluginRuntimeService owns the supervisor: activate spawns the child with its
granted permissions + decrypted instance config, deactivate kills it, status
and errors are persisted to the plugins / plugin_error_log tables, and active
plugins are booted on startup (OnModuleInit).
- Bidirectional RPC: the child now handles host→child invokes (routes/jobs) and
reports its declared routes on load; the supervisor gained invoke()/routesOf().
- /api/plugins/:id/* proxy controller — a single static route that matches the
plugin's declared routes, enforces per-route auth (auth:false routes are public
for OAuth callbacks/webhooks), forwards only a whitelisted request view (never
the session cookie), and strips unsafe response headers.
- Admin endpoints: POST :id/activate, POST :id/deactivate, GET/PUT :id/config —
instance settings with secret fields encrypted (apiKeyCrypto) and masked.
- Kill switch moved to its own module so it never collides with test config mocks.
Photo/calendar hook consumers are deferred to a later slice.
