/**
 * Collab API contract — single source of truth for the /api/trips/:tripId/collab
 * endpoints (shared notes + file attachments, decision polls, group chat with
 * reactions, link previews).
 *
 * Trip-scoped; mutations use 'collab_edit' (file uploads use 'file_upload'). The
 * legacy route (server/src/routes/collab.ts) wraps collabService and broadcasts
 * over WebSocket + fires chat/note notifications. Rows are wide and kept open;
 * the request schemas + the bespoke 400/403/404 controller messages pin the rest.
