Two follow-ups from the 12-lane TUI improvements dispatch:

1. auto-reviewer.sh — add --loop, --interval=<sec>, and --once flags so
   full-bringup.sh:771 (`auto-reviewer.sh --loop --interval=300`) keeps
   working after PR #126's rewrite to the --plan-slug contract. Default
   stays one-shot; --loop wraps main() in a while+sleep with rc warning
   on iteration failure so a transient claude error doesn't kill the
   ticker.

2. supervisor.sh — rename the documented classifier categories from
   working/asking/blocked/done to busy/asking/blocked/quiet so the
   canonical prompt heredoc matches the live classifier emitter at
   scripts/codex-fleet/lib/claude-supervisor-classifier.sh (and the
   legacy fixtures at scripts/codex-fleet/test/fixtures/
   claude-supervisor-classifier/). Updated examples + 3-strike-guard
   bullets to match the new names; semantics unchanged (busy = active
   progress, quiet = idle/completed).
