chore(deps): bump @opentelemetry/sdk-metrics from 2.8.0 to 2.9.0

[dependabot]

Bumps @opentelemetry/sdk-metrics from 2.8.0 to 2.9.0.

Release notes

Sourced from @​opentelemetry/sdk-metrics's releases.

v2.9.0

2.9.0

💥 Breaking Changes

• docs(shim-opentracing): Notice: The @opentelemetry/shim-opentracing package will be removed in SDK 3.x, planned for approximately September 2026.
  • The OpenCensus and OpenTracing compatibility requirements in the OpenTelemetry specification have been deprecated.

🚀 Features

• feat(sdk-metrics): add maxExportBatchSize option to PeriodicExportingMetricReader #6655 @​psx95
  • Optimized PeriodicExportingMetricReader.forceFlush to prevent redundant concurrent export cycles. Concurrent calls to forceFlush will now await any ongoing export and reuse a fresh export cycle if one is started concurrently by another caller. This ensures the latest metrics are always exported efficiently without triggering duplicate collection and export cycles.
• feat(sdk-trace): implement span processor metrics #6504 @​anuraaga
• feat(sdk-trace): add a new "sdk-trace" package to hold the Trace SDK, without environment variable configuration handling that belongs elsewhere #6775 @​trentm
  • "sdk-trace" will eventually replace all of "sdk-trace-base", "sdk-trace-node", and "sdk-trace-web".
  • The BatchSpanProcessor constructor call signature has changed in "sdk-trace". For example, before new BatchSpanProcessor(exporter, { maxQueueSize: 1000 }), after new BatchSpanProcessor({ exporter, maxQueueSize: 1000 }). #6817
  • The SimpleSpanProcessor constructor call signature has changed in "sdk-trace". For example, before new SimpleSpanProcessor(exporter), after new SimpleSpanProcessor({ exporter, selfObsMeterProvider: ... }). #6504
• feat(sdk-trace): add AlwaysRecordSampler #6188 @​majanjua-amzn

🐛 Bug Fixes

• fix(propagator-jaeger): do not throw on malformed percent-encoded uber-trace-id / uberctx-* headers during extract @​pichlermarc

🏠 Internal

• perf(sdk-metrics): defer allocation of HrTime to accumulation creation #6839 @​legendecas
• chore(*): migrate use of sdk-trace-base and sdk-trace-node to sdk-trace #6851 @​trentm
• perf(sdk-metrics): optionally capture active context for sync instruments #6848 @​legendecas
