Plugins can now render UI. Page plugins appear as a nav entry and open a full-page sandboxed iframe; the frame talks to TREK only over the postMessage bridge. - Server serves plugin client assets at /plugin-frame/:id/* with a strict path guard and a locked-down, per-plugin CSP (default-src none; connect-src limited to declared outbound hosts; sandbox WITHOUT allow-same-origin -> opaque origin, so the frame can't read the session cookie or the parent DOM). Global CSP frameSrc relaxed from 'none' to 'self' for exactly these frames. - GET /api/plugins feed lists active plugins for the client. - Client: pluginStore + PluginFrame (the trekBridge host) authenticates every inbound message by SENDER WINDOW IDENTITY (event.source), not by a claimed id or origin; pushes context (theme/locale/tripId/userId), validates navigation, renders notifications as text, resizes widgets, and proxies trek:invoke to the plugin's own routes host-side (session cookie stays with the host). - Page route /plugins/:id + Navbar nav injection for page plugins. Dashboard widget slot and the trek:request core-data bridge are deferred to a later slice.
