Batch-integrate finished runs — cyberine land

cyberine land collapses the whole landing leg (wait -> digest -> apply+commit per run -> one final typecheck for the batch) into a single command — the integration step of the two-turn dogfood protocol:

cyberine land <runId1> <runId2> ...        # land each run in order, commit per run, ONE final npm run typecheck
cyberine land <runId1> <runId2> --dry-run  # digests + apply checks only, no commits

Per run it waits for a terminal state, prints the compact digest, verifies the winning diff applies cleanly, applies + commits it, then runs ONE npm run typecheck for the whole batch (catches cross-run interactions per-run gates cannot see) and prints a summary table (runId, diffstat, commit, RISK flags). Stops on the first apply/typecheck failure and reports landed vs not landed. RunId prefixes resolve like cyberine apply.
