* fix(telemetry): use correct TopologyId field in integration test
The proto field was renamed from cluster_id to topology_id but the
integration test was not updated, causing a compilation error.
* ci: add telemetry integration test workflow
Runs the telemetry integration test (server startup, protobuf
marshaling, client send, metrics/stats/instances API checks) on
changes to telemetry/ or weed/telemetry/.
* fix(telemetry): improve error message specificity in integration test
* fix(ci): pre-build telemetry server binary for integration test
go run compiles the server on the fly, which exceeds the 15s startup
timeout in CI. Build the binary first so the test starts instantly.
* fix(telemetry): fix ClusterId references in server and CI build path
- Replace ClusterId with TopologyId in server storage and API handler
(same rename as the integration test fix)
- Fix CI build: telemetry server has its own go.mod, so build from
within its directory
* ci(telemetry): add least-privilege permissions to workflow
Scope the workflow token to read-only repository contents, matching
the convention used in go.yml.
* fix(telemetry): set TopologyId in client integration test
The client only populates TopologyId when SetTopologyId has been
called. The test was missing this call, causing the server to reject
the request with 400 (missing required field).
* fix(telemetry): delete clusterInfo metric on instance cleanup
The cleanup loop removed all per-instance metrics except clusterInfo,
leaking that label set after eviction.
