When the stop POST timed out (5s), lifecycle was set to 'idle' on error, allowing checkStatus to see running=true and reconnect SSE. Now: - stop .then() stays in 'stopping' on timeout/error instead of going idle - checkStatus skips reconnect when lifecycle is 'stopping' post-timeout but still transitions to idle when server confirms running=false - LOCAL_STOP_TIMEOUT_MS raised from 5s to 12s to match server cleanup time Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
