Release v0.7.2: safer delegation and worker review

[roodriigoooo]

Summary

• keep worker-to-parent traffic metadata-only and make ready review evidence-first
• separate loaded evidence from unresolved verdict attention
• clarify calm worker dock actions
• plan-gate built-in default workers
• prepare package, lockfile, CHANGELOG, and release notes for 0.7.2

Verification

• npm run check
• npm test
• npm run pack:dry

Release

After merge, push v0.7.2. The Release workflow verifies the package version, publishes npm with provenance, packs the artifact, and creates the GitHub Release from docs/releases/0.7.2.md.
