feat(uok): complete pipeline integration and close all parity gaps vs gsd2

- flags: gitopsTurnAction default → "commit" (ensures git history per turn)
- kernel: add runKernelLoop routing, parity label → "uok-kernel"
- auto: pass runKernelLoop at both call sites
- loop-adapter: already had writer token acquire/release (confirmed at parity)
- gate-runner: already had try/catch, dynamic ceiling, maxAttempts (confirmed)
- audit: isStaleWrite guard already present (confirmed at parity)
- plan-v2: add emptyGraph/sliceCount fields, isEmptyPlanV2GraphResult export,
  allow validating/completing-milestone with zero task nodes + slices present
- phases: add empty-graph recovery (invalidate-caches + re-derive) in runPreDispatch
- execution-graph: add ExecutionGraphSnapshot interface + buildExecutionGraphSnapshot
- auto-dispatch: wire buildDispatchEnvelope at all 3 dispatch exit points,
  emit dispatch-envelope audit event when gates or auditEnvelope enabled
