Test & Lint Summary

• buf generate buf.build/agynio/api --path agynio/api/gateway/v1 --include-imports
• go test ./... (passed: 7, failed: 0, skipped: 1)
• go vet ./... (no issues)

Config looks aligned with agynd-cli#113: Claude subprocess now has explicit OTEL exporters enabled and protocol forced to gRPC.

Minor note left inline about avoiding a hard-coded OTLP endpoint.

[nit] Consider changing the PR description from Refs #113 to Closes #113 so it auto-closes on merge.

Summary

• derive the OTLP endpoint from tracingproxy.ListenAddress

Test & Lint Summary

• buf generate buf.build/agynio/api --path agynio/api/gateway/v1 --include-imports
• go test ./... (passed: 7, failed: 0, skipped: 1)
• go vet ./... (no issues)

[noa-lucent]

Re-review after update: confirmed the Claude OTLP endpoint is now derived from tracingproxy.ListenAddress again, and the additional OTEL env vars match the issue spec (force gRPC OTLP traces; disable metrics/logs).
