The trust centerpiece: /reviews lists held agent actions for the scopes the caller may
approve. Each card shows the agent badge, action kind + risk (destructive flagged red),
an EDITABLE proposed artifact and child-task list (edits feed the edit-distance metric),
an expandable reasoning trace (pretty-printed), and Approve / Send back. Toasts surface
the recorded edit distance. New shadcn-style Textarea; nav gains "Review inbox".
Verified: npm run build green (TS strict, 1893 modules).
