AgentXchain v2.146.0

v2.146.0 ships BUG-51, the fast-startup watchdog follow-up to BUG-47. Ghost-dispatched turns that never attach a subprocess output path are now detected within 30 seconds instead of sitting in fake running state for roughly 10 minutes before stale-turn recovery begins. BUG-51 and BUG-47 both remain open pending tester verification per discipline rule #12. BUG-48, BUG-49, and BUG-50 remain open pending their earlier tester verification on v2.145.0.

Bug Fixes

• BUG-51 fast-startup ghost-turn watchdog: a new 30-second startup watchdog detects ghost-dispatched turns with no dispatch-progress, no staged result, and no durable turn activity, transitions them to retained failed_start, emits turn_start_failed, and surfaces explicit reissue-turn --reason ghost guidance in status, resume, and step --resume.

• BUG-51 budget reservation release: ghost-turn and stale-turn reconciliation now release the failed turn's USD budget reservation immediately on detection so reissued turns do not compete with stale reservations.

• BUG-47 tester-sequence split hardening: stale-turn beta-tester scenarios now seed dispatch-progress before backdating timestamps so BUG-47 covers the "subprocess started, then went silent" path while BUG-51 owns the "subprocess never attached" path.
