The engine already runs a StuckTaskDetector with a configurable per-task
heartbeat (default 1 hour) and aborts triage/executor sessions through
AbortSignal when it judges them quiet. pi-claude-cli forwards that signal to
the subprocess. The 300s subprocess-level inactivity timeout was a redundant,
much-tighter shadow that kept killing Sonnet 4.6 mid-thinking on the 40k-char
triage prompt — exactly what the engine-level detector is designed not to do.
Move the local timeout to 30 minutes purely as a last-resort guard for embeds
that don't pass an abort signal. Stuck-detection responsibility now lives in
the caller, where it can be configured per task.
