Akka.TestKit.Xunit2 -> Akka.TestKit.Xunit 1.5.62 (xunit.v3 TestKit; needs xunit.v3 3.2.2, set via
VersionOverride on the four projects). Removes the xunit 2.9.3 pin. IAsyncLifetime returns ValueTask,
SqlServerFactAttribute gains the source-info ctor, and xUnit1051 call sites pass
TestContext.Current.CancellationToken. Test counts unchanged.

Review 02 P5. OpcUaPublishActor ran the whole apply — DeploymentArtifact
.Open, ParseComposition, AddressSpacePlanner.Compute and the sink
materialisation — on the opcua-synchronized-dispatcher, so a large
artifact serialised every live value batch (and, because the node
manager lock is the SDK's, every client Publish) behind the parse.
StartRebuild now runs Open + ParseDataPlaneAuthority + ParseComposition
+ Compute in Task.Run and pipes a PlanReady (or PlanFailed) back to Self;
only ApplyPlan — the sink passes — runs on the actor thread. Rebuilds are
applied strictly in arrival order (a plan is a diff against _lastApplied,
which only the apply advances): one in flight, later ones queue in
_pendingRebuilds while value/status batches keep flowing. The apply is
closed (CompleteAddressSpaceApply) and the RebuildCompleted reply sent on
every path, PlanFailed included. The bytes-less ConfigDb fallback
(LoadArtifact / LoadLatestArtifact) is deleted: it had no production
producer and would have blocked the pinned thread on central SQL; the
dbFactory Props/ctor parameter is kept for wiring compatibility (F4).
Tests: OpcUaPublishActorOffThreadPlanTests — a value batch sent right
after a 50k-tag rebuild lands before that rebuild's first materialise
call (positive control: all 50k tags still materialise); back-to-back
rebuilds apply in arrival order (the second diffs against the first);
unreadable bytes answer degraded with nothing torn down. The rebuild /
apply-failure suites now hand the actor the artifact bytes every
production producer carries (SealArtifact records them; Rebuild(dep)).
