Fix audit workflow agent startup failure when OTLP secrets are unset

[Copilot]

Bug Fix

What was the bug?

The agent job in the Copilot token audit workflow failed before the prompt executed. The generated workflow passed empty OTLP endpoint/header values into MCP Gateway, and MCP Gateway rejected the invalid OpenTelemetry config during startup.

How did you fix it?

• Removed optional OTLP wiring from the audit workflow source

  • Dropped the observability.otlp block from the audit workflow markdown so the workflow no longer emits empty OTLP settings when those secrets are not configured.

• Regenerated installed workflow artifacts

  • Recompiled the corresponding lock files so the checked-in executable workflows match the updated source and no longer include:
    • OTEL_EXPORTER_OTLP_ENDPOINT
    • OTEL_EXPORTER_OTLP_HEADERS
    • GH_AW_OTLP_ENDPOINTS

• Scope of change

  • Limited to the Copilot token audit workflow in both source locations used by this repo:
    • workflows/copilot-token-audit.md
    • .github/workflows/copilot-token-audit.md
