Subject: refactor: split agent detection by agent

Move screen detection into per-agent modules and keep visible-state arbitration centralized in terminal state.

Tighten Codex prompt-scoped working detection and Claude hook/screen recovery for stale blocked and idle reports.

Add a focused just recipe for single-test runs.
