Merge main into v2-flow, incorporating: - Set maxDuration: 'max' in vc-config for workflow functions (#1420) Conflict resolution: keep V2 code (no separate step.func), add maxDuration to the combined flow.func config across all builders. Also fix: hook_completed → hook_received in onUnconsumedEvent skip logic (hook_completed is not a valid event type). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
