The community feedback endpoint was registered as /api/ui-feedback in
the Go API but the plan and annotation.ts client both use /api/feedback.
Rename the route and update agentation-overlay.ts to match. Add a
route-level test asserting the canonical path and that the old path
returns 404.

Mounts the Agentation React component (v3) as a thin overlay on the vanilla TS
app via a React root shim. The toolbar appears bottom-right and lets users click
any element, annotate it, and generate structured markdown for AI agent feedback.
Submissions are persisted in localStorage and POSTed to /api/ui-feedback when
the API is available.
