fix: pass OpenTelemetry environment variables to Claude Code subprocess (#886)

* fix: pass OpenTelemetry environment variables to Claude Code subprocess Environment variables set in workflow's step `env:` block were not being passed to the Claude Code subprocess because composite actions only forward explicitly referenced environment variables. This fix adds references for telemetry-related environment variables: - CLAUDE_CODE_ENABLE_TELEMETRY - OTEL_METRICS_EXPORTER - OTEL_LOGS_EXPORTER - OTEL_EXPORTER_OTLP_PROTOCOL - OTEL_EXPORTER_OTLP_ENDPOINT - OTEL_METRIC_EXPORT_INTERVAL - OTEL_LOGS_EXPORT_INTERVAL - OTEL_RESOURCE_ATTRIBUTES Co-Authored-By: 조상연[플레이스 AI] <sang-yeon.cho@navercorp.com> Co-Authored-By: csy1204 <josang1204@gmail.com> Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * test: add tests for OTEL environment variables passthrough Verify that telemetry-related environment variables are correctly passed through to sdkOptions.env when set in process.env.

This variable is needed for authentication when connecting to OTLP endpoints that require bearer tokens or other credentials.
