Agent Browser Leak Fix & Scheduler Hardening

Leaked agent-browser Chrome processes that outlived their worker sessions — sometimes pegging a CPU core indefinitely — are now reaped automatically by a new vector in the hourly orphan sweep, which targets runaway or idle Chrome-for-Testing instances while leaving personal Chrome untouched. Workers also receive an idle-timeout environment variable at dispatch so agent-browser shuts itself down after 5 minutes of inactivity on supported versions. Two scheduler fixes round out the release: phantom ticket directories (like .catalyst) no longer poison board-health checks, and a transient source conflict during dispatch-time rebase now triggers a single retry against a fresh base before parking the ticket as needs-human.
