clear_inbox_view

Acknowledge your global plus selected-project inbox view in bounded raw-key windows. Account read/write grant and current project-open access required, including viewers acknowledging their own notifications. Explicit viewBoardId, independent of ambient context. limit=1..500 per stream; scans at most 2*(limit+1) keys, changes at most 2*limit rows. nextCursor binds the view and first-call cutoff; later arrivals remain unread. Follow even pages with marked=0. Retries of the same cursor are harmless. No deletion, retention pruning, totals, project content writes or receipt. Only actual changed IDs are pushed to your inbox.
