Joseph Doherty ef22a61c39 v2 mxgw migration — Phase 1+2+3.1 wiring (7 PRs)
Foundational PRs from lmx_mxgw_impl.md, all green. Bodies only — DI/wiring
deferred to PR 1+2.W (combined wire-up) and PR 3.W.

PR 1.1 — IHistorianDataSource lifted to Core.Abstractions/Historian/
  Reuses existing DataValueSnapshot + HistoricalEvent shapes; sidecar (PR
  3.4) translates byte-quality → uint StatusCode internally.

PR 1.2 — IHistoryRouter + HistoryRouter on the server
  Longest-prefix-match resolution, case-insensitive, ObjectDisposed-guarded,
  swallow-on-shutdown disposal of misbehaving sources.

PR 1.3 — DriverNodeManager.HistoryRead* dispatch through IHistoryRouter
  Per-tag resolution with LegacyDriverHistoryAdapter wrapping
  `_driver as IHistoryProvider` so existing tests + drivers keep working
  until PR 7.2 retires the fallback.

PR 2.1 — AlarmConditionInfo extended with five sub-attribute refs
  InAlarmRef / PriorityRef / DescAttrNameRef / AckedRef / AckMsgWriteRef.
  Optional defaulted parameters preserve all existing 3-arg call sites.

PR 2.2 — AlarmConditionService state machine in Server/Alarms/
  Driver-agnostic port of GalaxyAlarmTracker. Sub-attribute refs come from
  AlarmConditionInfo, values arrive as DataValueSnapshot, ack writes route
  through IAlarmAcknowledger. State machine preserves Active/Acknowledged/
  Inactive transitions, Acked-on-active reset, post-disposal silence.

PR 2.3 — DriverNodeManager wires AlarmConditionService
  MarkAsAlarmCondition registers each alarm-bearing variable with the
  service; DriverWritableAcknowledger routes ack-message writes through
  the driver's IWritable + CapabilityInvoker. Service-raised transitions
  route via OnAlarmServiceTransition → matching ConditionSink. Legacy
  IAlarmSource path unchanged for null service.

PR 3.1 — Driver.Historian.Wonderware shell project (net48 x86)
  Console host shell + smoke test; SDK references + code lift come in
  PR 3.2.

Tests: 9 (PR 1.1) + 5 (PR 2.1) + 10 (PR 1.2) + 19 (PR 2.2) + 1 (PR 3.1)
all pass. Existing AlarmSubscribeIntegrationTests + HistoryReadIntegrationTests
unchanged.

Plan + audit docs (lmx_backend.md, lmx_mxgw.md, lmx_mxgw_impl.md)
included so parallel subagent worktrees can read them.
