 * gstack-pr-wait — watch one pull request and print one line per real event.
 *
 *   gstack-pr-wait <pr> [--repo owner/name] [--until green|ready|any-change] [--interval SECONDS] [--timeout MINUTES] [--exclude CHECK,...]
 *
 * Exit 0 when the --until condition is met or the PR merged, 1 when it needs
 * action (PR_WAIT_BLOCKED), 2 on bad input, a duplicate watcher or a local
 * error (PR_WAIT_REFUSED). The loop is synchronous (spawnSync, Bun.sleepSync),
 * so signals keep their default disposition: Ctrl-C and kill end the process
 * at once and the next watcher takes over the dead pid's lock. Review-bot lists: `gstack-config set pr_wait_gating_bots`
 * and `pr_wait_advisory_bots`. Logic: lib/pr-wait.ts and lib/pr-wait-github.ts.
 *
 * Design ported from tstack's pr-wait (t3dotgg/tstack, MIT, Copyright (c) 2026
 * Theo Browne; NOTICE.md). Docs: docs/troubleshooting.md#gstack-pr-wait
