Actively exercise the iterm-config hook stack end-to-end. Flashes the three tab colors (idle → processing → waiting) on the current tab and verifies each round-trips through the daemon. Use when the user asks "is the iterm thing actually working", "test the iterm hooks", "/iterm-diagnose", or wants confirmation after a change. Different from /iterm-status (passive snapshot) — this skill performs writes and briefly changes the visible tab color. Add the `--restart` arg to also kill the daemon and verify the launchd watchdog respawns it (~30s extra).

Active end-to-end test. Flashes colors on the current tab, verifies each pushes through to iTerm2 via the daemon, and reports pass/fail per step.
