fix(alarms): #647 review — Raise on an active condition is a re-statement; FOCAS outage quality + health

Browse Source 
MAJOR-1: a deploy that changes a driver's config respawns it, and the fresh instance's empty told
record re-sent Raise for every still-active alarm, un-acking acknowledged conditions and writing a
duplicate "Activated" alerts row. NativeAlarmProjector now treats Raise on an already-active
condition as a re-statement (keeps Acked; ForwardNativeAlarm skips the alerts row); only Retrigger
(or inactive->active) un-acks. Sources whose upstream ack state is authoritative send Retrigger for
an unacked re-statement: OpcUaClient on first sight (no prior told), Galaxy for an unacked active
snapshot entry. Runtime E2E drives a FRESH FOCAS driver after a redeploy and asserts the ack survives.

MAJOR-2: a failed FOCAS alarm read annotates each subscribed condition BadNoCommunication once per
outage (#626 quality-only path) with one Warning (MINOR-6), lifted to Good on recovery; failed alarm
reads degrade driver health with LastSuccessfulRead frozen (successful ones advance it), so an
alarm-only driver trips the #527 comms-loss watchdog.

MINOR-3 CLAUDE.md #630 bullet; MINOR-4 split line; MINOR-5 a non-empty cnc_rdalmmsg2 payload that
fits neither stride throws; MINOR-7 value-tag + parsed-address tables are built and swapped, never
cleared in place under the retained poll engine. Docs corrected (FOCAS.md, AlarmTracking.md, CLAUDE.md).
