그 외 기록된 변경 9건 전체fixes 7 · additions 2

- cmd/mdatagen: Replace the O(n) scan in generated recordDataPoint with an O(1) hash lookup, fixing an O(n²) cost per scrape when many data points land on one resource. (#15912)
- cmd/mdatagen: When both migration gates are enabled, only the latest metric with its v1 attributes is emitted (legacy attributes are no longer included). (#15979)
- pkg/exporterhelper: Fix sending queue deadlocks when blocked offers are cancelled with block_on_overflow enabled. (#15700)
- pkg/exporterhelper: Drop only the oversized profile when splitting a profiles batch, instead of discarding every profile queued behind it (#16087) Same fix as
- pkg/exporterhelper: Drop only the oversized span when splitting a traces batch, instead of discarding every span queued behind it (#16087) Same fix as
- pkg/pprofile: Use the profiles dictionary for resource and scope attribute strings sent over OTLP/gRPC. (#15861) The OTLP/gRPC profiles client now interns attribute strings before transmission, matching the OTLP/HTTP path. The server resolves the references before exposing pdata to consumers.
- pkg/otelcol: Redact config opaque MapList values in unexpanded configuration snapshots (#15980)

- cmd/builder: Add dist.resource.detection.detectors to the builder config, letting distributions opt into a smaller set of resourcedetectionprocessor detectors via generated go build tags. (#16075)
- pkg/pprofile: Implement Profiles development-version metadata in the OTLP receiver and exporters. (#16147, #16009) The receiver rejects malformed, repeated, or unsupported versions before decoding. OTLP exporters send the version associated with their compiled-in Profiles schema. The version is not configurable, and existing clients without metadata identify the initial development version.
