Refactor 19 workflows to use shared guard-otlp import bundle

[Copilot]

19 workflows were repeatedly importing shared/github-guard-policy.md and shared/otlp.md together. This change introduces a single shared bundle for that pair and migrates all known occurrences to reduce duplication and align with existing shared-import patterns.

• New shared component

  • Added .github/workflows/shared/guard-otlp.md to encapsulate:
    • shared/github-guard-policy.md
    • shared/otlp.md

• Workflow import migration (19 files)

  • Replaced paired imports in:
    • auto-triage-issues.md
    • daily-agent-of-the-day-blog-writer.md
    • daily-doc-updater.md
    • daily-issues-report.md
    • discussion-task-miner.md
    • issue-arborist.md
    • issue-monster.md
    • issue-triage-agent.md
    • org-health-report.md
    • smoke-agent-public-approved.md
    • smoke-agent-scoped-approved.md
    • smoke-copilot-aoai-apikey.md
    • smoke-copilot-aoai-entra.md
    • smoke-copilot.md
    • stale-repo-identifier.md
    • weekly-blog-post-writer.md
    • weekly-issue-summary.md
    • weekly-safe-outputs-spec-review.md
    • workflow-generator.md

• Compiled output synchronization

  • Updated corresponding .lock.yml files generated from the migrated workflows.

• Fixes [refactoring] skill: create shared/guard-otlp.md bundle for 19 workflows using github-guard-policy.md+otlp.md #47458
