"""Start the daemon only when an agent app is actually open.

Run periodically by the scheduled task the installer creates (Windows
Task Scheduler / macOS launchd StartInterval) -- NOT at login. Checks
for watched agent processes or fresh agent file activity and brings the
daemon up via lightctl.ensure_daemon(); exits immediately otherwise, so
nothing stays resident while no agent is around.

Hooked agents (Claude Code, Cursor, Codex notify) still start the daemon
instantly through their hooks; this trigger only covers hook-less apps
(the Codex/ChatGPT app, Gemini, opencode, ...), with a worst-case delay
of one trigger interval.
