Assessment: 🟢 APPROVE

This PR is a clean vendor dependency bump:

• go.opentelemetry.io/otel → v1.44.0
• go.opentelemetry.io/contrib → v0.69.0
• Related gRPC and semconv updates

Both diff chunks were reviewed in full. The added code introduces consistent, correct patterns throughout:

• Early-exit .Enabled(ctx) guards before recording metrics (correct performance optimization)
• clear(*o) before *o = (*o)[:0] in sync.Pool defer blocks (correct GC hygiene, prevents stale interface pointer retention)
• New *Observable wrapper types all follow the established nil-meter guard pattern
• Explicit histogram bucket boundaries added to duration instruments
• All new constructors correctly propagate errors and fall back to noop instruments on failure

No bugs, logic errors, nil dereferences, race conditions, or resource leaks were found in any added code.
