Enable gh-aw detection coverage on Smoke CI and four analysis workflows

[Copilot]

Deep-report flagged five workflows with missing/disabled detection, creating a coverage gap in high-signal audit/analysis paths and the high-traffic smoke workflow. This change enables gh-aw-detection across all flagged workflows and turns on Smoke CI threat detection, then regenerates compiled lockfiles.

• Detection enablement

  • smoke-ci.md: set features.gh-aw-detection: true and safe-outputs.threat-detection: true
  • prompt-clustering-analysis.md: add features.gh-aw-detection: true
  • typist.md: add features.gh-aw-detection: true
  • agentic-token-audit.md: add features.gh-aw-detection: true
  • github-mcp-structural-analysis.md: add features.gh-aw-detection: true

• Compiled workflow updates

  • Regenerated lockfiles for the five updated markdown workflows so runtime behavior matches frontmatter changes.
