80104caf09 sidecar: switch Wonderware historian sidecar from x86 to x64 
The sidecar was set to PlatformTarget=x86 + Prefer32Bit=true to mirror
v1's Driver.Galaxy.Host bitness, which itself was x86 only because of
MXAccess COM. PR 7.2 retired Galaxy.Host, so that constraint is gone.

AVEVA Historian 2020 ships an x64 build of every SDK assembly the
sidecar needs (lib\aahClientManaged.dll + aahClient.dll + aahClientCommon.dll
sourced from C:\Program Files (x86)\Wonderware\Historian\x64\; the
remaining three SDK assemblies — Historian.CBE / DPAPI /
ArchestrA.CloudHistorian.Contract — are pure-managed AnyCPU and load
in either bitness). Drop PlatformTarget to x64 on both the sidecar
project and its test project; running 37/37 historian tests + the
live install confirms the SDK loads and serves the named pipe in a
64-bit-native process.

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.
