Subject: [PATCH] clients: regenerate Python + Go protos for alarm RPCs (PR
 E.1)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pure mechanical regen following PR A.1 (alarm-transition event family
+ AcknowledgeAlarm / QueryActiveAlarms public RPCs). Ran:

- clients/python/generate-proto.ps1 → mxaccess_gateway_pb2.py +
  mxaccess_gateway_pb2_grpc.py.
- clients/go/generate-proto.ps1 → mxaccess_gateway.pb.go +
  mxaccess_gateway_grpc.pb.go + galaxy_repository.pb.go (whitespace
  diff from upstream protoc minor version).

The .NET binding regenerates on csproj rebuild via Grpc.Tools — its
artifact (Generated/MxaccessGateway*.cs) was already updated as part
of A.1's commit. Java + Rust regen happens at build time via the
gradle plugin / build.rs respectively, with no committed output to
update.

Smoke-imported the regenerated Python descriptors:
  OnAlarmTransitionEvent.DESCRIPTOR.fields → alarm_full_reference,
    alarm_type_name, category, current_value, description, ...
  AcknowledgeAlarmRequest.DESCRIPTOR.fields → alarm_full_reference,
    client_correlation_id, comment, operator_user, session_id
  ActiveAlarmSnapshot.DESCRIPTOR.fields → alarm_full_reference,
    alarm_type_name, category, current_state, current_value, ...

PRs E.2 - E.6 layer hand-written SDK methods on top of the regenerated
types — those land per-language as separate PRs.
