feat(author-workflow): enforce exact issue lock before branch/commit/push/PR (Closes #204)

- Upgrade SKILL.md §K compact format to the issue #182 canonical field set
  (Task/Repo/Role/Identity/Issue-PR/Branch-SHA/Files/Validation/Mutations/
  Current status/Blockers/Next/Safety) plus role-specific field lists for
  review/merge, author, and queue/inventory tasks.
- Point the review-pr, merge-pr, and start-issue template handoff lines at
  the exactly-titled Controller Handoff section with their role fields.
- Add review_proofs.assess_controller_handoff(): reports without the exact
  section are 'missing' (downgraded), present-but-partial are 'incomplete'
  with the absent fields listed, and role extras are enforced per role.
- Add TestControllerHandoff (8 tests) including a SKILL.md doc-contract
  test so the documented requirement cannot silently rot.

The handoff supplements the full report; full-report validation rules are
unchanged.

Closes #182
