Adds OTLP observability support to all GitHub Agentic Workflows via a single shared fragment, activated automatically when GH_AW_OTEL_ENDPOINT and GH_AW_OTEL_AUTHORIZATION secrets are present.

Changes

• New fragment gh-aw-fragments/observability.md — holds the shared observability.otlp configuration referencing the two secrets as optional inputs; no-ops gracefully when secrets are absent
• 57 workflow .md files updated — all gh-aw-* and internal workflow sources import gh-aw-fragments/observability.md as their first import
• 56 .lock.yml files recompiled — each lock file now declares GH_AW_OTEL_ENDPOINT and GH_AW_OTEL_AUTHORIZATION as required: false workflow secrets and wires OTEL_EXPORTER_OTLP_ENDPOINT / OTEL_EXPORTER_OTLP_HEADERS / GH_AW_OTLP_ENDPOINTS env vars
• gh-agent-workflows/DEVELOPING.md — fragment table updated to document observability.md

Fragment

# gh-aw-fragments/observability.md

observability:
  otlp:
    endpoint:
      - url: ${{ secrets.GH_AW_OTEL_ENDPOINT }}
        headers:
          Authorization: ${{ secrets.GH_AW_OTEL_AUTHORIZATION }}

Consumer repos that want telemetry only need to set two repository secrets — no workflow changes required.
