Native conditions support AddComment / commented Acknowledge, so the comment (and its
ClientUserId) is condition state the rebuild dropped. And the deferred restore report
re-stamped Time with the carried instant even when a client method call had reported a
newer event in the restore->complete window; it now reports at the node's current Time.

#641 keeps the projector's prior state across a deploy instead of resetting it to the
acked default. The projector never saw a client's ack (the SDK applies it to the node and
the host only routes it), so a Clear after ack+deploy now projected Acked=false and
un-acknowledged the operator's ack - previously masked by the per-deploy reset.

Now that ALMD transitions route, a re-subscribe (every reconnect, every alarm-set change)
started from an empty per-subscription record and re-RAISED every still-faulted alarm,
which the host projects as Active+unacked - un-acknowledging a condition the server had
just carried across the rebuild with its client ack. The record is now driver-owned and
pruned to the new set, mirroring MTConnect's _deliveredConditions.

Found while verifying item 4 of #641. The host routes a native alarm transition
on an exact ConditionId == RawPath match (DriverHostActor.ForwardNativeAlarm),
but AbCipAlarmProjection emitted "{ref}#active" and no Kind, so every ALMD
raise/clear was dropped as "no alarm condition" — and even if routed, an
Unspecified kind projects no state change. It now reports the subscribed
reference (the RawPath) and Raise/Clear. A host test pins that a decorated id
is dropped.
FOCAS has the same id shape plus a device filter keyed by host address (a
RawPath subscription polls nothing); it needs a mapping decision and is
documented in docs/drivers/FOCAS.md rather than patched here.

The driver cleared its whole "last told" record whenever the subscribed alarm
set changed, assuming the rebuild that accompanies an alarm-bearing delta had
reset every condition node. The server now carries each surviving native
condition's state (acknowledgement included) across the rebuild, so re-raising a
survivor would un-acknowledge it. Only entries that left the set are dropped; a
condition that comes back later is told again onto its fresh node.

DriverHostActor cleared NativeAlarmProjector's per-condition prior state on
EVERY apply, so after any deploy a driver Acknowledge of a still-active alarm
projected Active=false (writing it inactive) and a Clear of an unacknowledged
alarm projected Acked=true (silently acknowledging it). The projector is now
pruned to the conditions the new composition still carries (RetainOnly).

A full RebuildAddressSpace recreated every native Part 9 condition inactive +
acknowledged, and when the alarm-tag set was unchanged (e.g. one
UnsTagReference added to an alarm-bearing raw tag) nothing re-told the new node
its state: the host does not re-subscribe for an unchanged set, and Galaxy /
OpcUaClient have no snapshot to replay anyway. Active alarms read normal until
their next device transition.
OtOpcUaNodeManager now captures each NATIVE condition's live state (from the
node, so a client-applied ack is kept) before the rebuild clears, restores it
when the same id is re-materialised native in the same apply, and reports ONE
condition event per restored off-normal condition at the new
IOpcUaAddressSpaceSink.CompleteAddressSpaceApply (after notifier wiring).
Unclaimed captures are discarded there, so a later re-add is fresh. Quality is
carried silently for normal conditions too (it is only re-annotated on a
connectivity edge). Scripted conditions are untouched (#487 re-asserts them).
OpcUaPublishActor calls CompleteAddressSpaceApply at the end of every apply.

OtOpcUaNodeManager.MapSeverity re-bucketed every projected severity onto the
SDK's five EventSeverity values (<800 -> 700, else 900), defeating #626's exact
OpcUaSeverity: an MTConnect Fault (800) read and evented as 900; a scripted
alarm graded 1000 published 900 while /alerts said 1000; a native Low (200)
published 300. EventSeverity merely names points on the 1..1000 scale, so the
node now carries the value clamped to 1..1000 (ToPart9Severity), at
materialise, projection and in the delta gate.
MTConnect wire test now asserts Fault ActiveState=true/Severity=800 and the
Normal clear ActiveState=false/Retain=false/Severity=800.

EventFilter.AddSelectClause(type, "ActiveState/Id") does not split the string;
it selects a single QualifiedName named "ActiveState/Id", which no event carries.
AckedState/Id, ActiveState/Id and EnabledState/Id therefore always arrived null
and Client.CLI 'alarms' (and Client.UI) reported every alarm inactive and
unacknowledged while a direct Read said Active. Pre-existing since a2883b82;
server-side event delivery was correct (proven with two-element select clauses,
incl. after #629). Select them with explicit two-element browse paths.
Over-the-wire test drives OpcUaClientService.SubscribeAlarmsAsync against the
in-process server (native + scripted); ServerEventRig now also selects
ActiveState/Id, Severity and Retain.

- Unavailable keeps an ACTIVE condition active: quality-only BadNoCommunication; on data
return same statement => quality-only Good, Normal => Clear, different => Retrigger.
- A changed alarm reference set (alarm-bearing delta = full rebuild) clears the whole
last-told record so every active condition is re-asserted; the same set keeps it.
- Quality-only events go through the host's AlarmQualityUpdate path, never a projected
snapshot (which could ack a retained unacked condition or rewrite message/severity).
- Deterministic tie-break between equal-level conditions (ordinal nativeCode, then type).
- Dedup key is level+nativeCode+nativeSeverity+qualifier; a text-only change updates nothing.

MTConnectConditionAlarmWireTests drives a scripted Agent's Fault/Normal through the real
driver, NativeAlarmProjector and sink to a client event subscription on the raw device
folder. docs/drivers/MTConnect.md replaces 'CONDITION v1: plain String' with the alarm
mapping, opt-in authoring, multi-condition, ack, replay and comms-loss behaviour, and a
live-check recipe; EVENT vocabularies as enumerations marked won't-fix. AlarmTracking.md
lists the MTConnect source and the two new AlarmEventArgs fields.

New() ran FindNodeInAddressSpace under Lock, taking other node managers' locks (lock-order
risk); the three AlarmConditionType_ShelvingState_* ids are now a static set. Adds wire tests:
TimedShelve/Unshelve by the condition's own instance method ids (object = condition or its
ShelvingState) succeed and report, and a ShelvedStateMachineType_* id call is pinned as
BadMethodInvalid with a positive control.

The parser keeps a condition's text, nativeCode, nativeSeverity, qualifier and type. A new
MTConnectConditionTracker applies MTConnect's multi-condition semantics (per-nativeCode
activation/clearing across /sample deltas, /current baseline reset, Unavailable), and
MTConnectConditionAlarmMapper turns tracker state into Part 9 transitions: Warning=500,
Fault=800, Normal=clear, Unavailable=inactive + BadNoCommunication; escalation or a new
code retriggers. The driver implements IAlarmSource keyed by the alarm tag's RawPath,
diffs against what the server was actually told (only when a handler is attached), so a
reconnect/re-baseline never re-raises an unchanged condition and a missed transition is
delivered on the next subscribe. Ack is a no-op success. Existing CONDITION String tags
are unchanged; a tag becomes an alarm only via the standard TagConfig 'alarm' object.

AlarmEventArgs gains optional OpcUaSeverity (supersedes the four-bucket mapping, clamped
1..1000) and QualityStatusCode (projected onto the condition's Quality). An Unspecified-kind
event carrying a quality is a quality-only annotation: the host updates the condition but
publishes no alerts row. Both default null, so every existing native source is unchanged.

Create(assignNodeIds: true) asked CustomNodeManager2.New, whose default returns the
node's current id, so every condition child kept the type's ns=0 instance-declaration id
(or an SDK-generated ns=0 number): translate of a child path returned BadNoMatch and a
Read of a browsed child id was BadNodeIdUnknown or served from the TYPE (UnshelveTime 0
on a condition timed-shelved for a minute), bypassing the data-plane ACL.
OtOpcUaNodeManager.New now derives {conditionId}/{browsePath} in the condition's
namespace, so the ACL scope of a child is its condition's scope plus the path. The
ShelvingState methods adopt their original AlarmConditionType_ShelvingState_* id as
MethodDeclarationId so clients calling them by that id still resolve. Condition removal
and rebuild forget the whole PredefinedNodes subtree so a removed condition's children
stop answering.

Live-measured on docker-dev: the backdrop was viewport-wide (1911px) but started at the
panel's left edge (241px) because the theme's .rise animation (fill-mode both) leaves an
identity transform on section.panel, re-basing position:fixed descendants. Override the
fill mode to backwards; drops the speculative backdrop/dialog sizing overrides.
