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

* 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.

* fix: add missing OTEL_EXPORTER_OTLP_HEADERS environment variable

Add OTEL_EXPORTER_OTLP_HEADERS to the list of OpenTelemetry environment
variables passed through to the Claude Code subprocess. This variable is
needed for authentication when connecting to OTLP endpoints that require
bearer tokens or other credentials.
