Drives the project's review⇄implementation cycle. Five subcommands — verify (check), result (record), close (wrap up), request (ask for review), fix (address findings). Role separation between an implementation session and a review session, turned into runnable steps. With no argument, inspect repo state (presence of docs/review-request-* and docs/review-*) and propose which subcommand fits.

Runs one triad session's side of the review⇄implementation loop against the triad server. With `register worker|reviewer <session-id>`, join a role and start long-polling for instructions. On each instruction, run the matching triad-plan subcommand (verify/result/fix/request/close), then report /done and wait again. This is the session-side loop of docs/design.md §6; the server (triad-server) owns handoff and command approval.
