MapStatusCode returned Uncertain for any non-zero non-Bad code, so GoodLocalOverride,
GoodClamped and info-bit Good variants degraded to Uncertain. Now top two bits decide:
00 Good, 01 Uncertain, 10/11 Bad (BadResourceUnavailable stays Bad, #112 untouched).
The SDK IsGood/IsUncertain(uint) helpers were tried first and failed the subcode tests,
so an explicit mask is used. MxGateway mapper uses the OPC-DA quality byte (>=192 Good)
and is not affected.

OtOpcUa's out-of-process script runner publishes 0x80040000 with a null value.
- OpcUaDataConnection: logs entry/recovery once per tag, names the symbolic
status in read errors; never a disconnect (not in the reconnect status set).
- InstanceActor: a Bad update with no value is a quality-only transition
(keep value, quality Bad, stream publish, no script/alarm/waiter re-eval),
matching the connection-drop rule. Bad with a value is unchanged.

Remove project bookkeeping citations from shipped code comments across the
solution: hyphenated task IDs (WP-14, StoreAndForward-025), milestone/task/
issue refs (M3, Task 4, Audit Log #23, #21), Bundle X task-bundle labels,
and C/D/K/S/T phase labels.
Comment text only — no code logic, string/log literals, or XML-doc structure
changed. Genuine descriptions are preserved (only the citation is stripped),
and technical lookalikes are retained (UTF-8, SHA-256, T00:00:00, M365,
UTC-5, pre-C4/pre-C5 schema versions). Flagged by the new CommentChecker
TaskReferenceInComment / TrackingReferenceInComment checks plus targeted
grep passes; full solution builds clean, append-only guard tests pass.
Resolve all 622 issues flagged by the enhanced CommentChecker: add missing
<returns> tags (incl. the standard phrasing on non-generic Task methods),
add missing <summary> tags, and replace misused/redundant <inheritdoc/> on
members that override or implement nothing with real documentation.
Documentation-only — no behavior change; solution builds clean.
Adds IAlarmSubscribableConnection to OpcUaDataConnection, IOpcUaClient alarm
subscription methods, and RealOpcUaClient A&C event monitored-item +
EventFilter + ConditionRefresh snapshot, mapping fields via OpcUaAlarmMapper.
Behavior verified against a live A&C server in Task 28; mapper unit-tested.
