fix(enrichment): detect quoted workflow uses keys

[JSONbored]

Motivation

• The unpinned-action analyzer used a line regex that required an unquoted literal uses: token and failed to detect valid YAML variants like uses : or quoted keys, allowing bypasses of the unpinned-action check.

Description

• Relax the USES_RE to accept optional key quotes and optional whitespace before the colon so YAML-equivalent uses, uses :, "uses":, and 'uses' : forms are detected (review-enrichment/src/analyzers/actions-pin.ts).
• Add a regression test exercising uses :, "uses":, and 'uses' : forms to ensure detection and line-citing remain correct (review-enrichment/test/enrichment.test.ts).

Testing

• Ran the review-enrichment unit suite with npm --prefix review-enrichment test, which passed all tests.
• Attempted the full local gate via git diff --check && npm run test:ci; earlier checks completed but the test:coverage stage hung in this environment and the run was terminated (partial progress observed before termination).
• Ran npm audit --audit-level=moderate, which failed due to the npm registry audit endpoint returning 403 Forbidden in this environment.

Contributor next steps

• Treat this as maintainer-lane context rather than normal contributor-lane activity.
• Explain no-issue PR.
• Review top overlaps.
• Add scope summary.
• Fix blocker.
• Expect slower review.
• Refresh registry data or choose a registered active repo.
• Link the issue being solved, or explicitly explain why this is a no-issue PR.
• Check active issues and PRs before submitting.

Signal definitions

• Related work = same linked issue, overlapping active PRs, or title/path similarity.
• Review load = cached public PR metadata such as size labels, changed paths, and preflight status.
• Open PR queue = repo-wide review pressure; it is not a PR quality failure.
• Contributor context = public GitHub/Gittensor identity context; non-Gittensor status is not a blocker.
