fix(skills): address code-review findings from PR #2007 review

- Remove name/description from step frontmatter (STEP-06)
- Add explicit HALT before user menu in step-01 (STEP-04)
- Escape story-id as template placeholder (REF-01)
- Handle untracked files in file-list diff mode (P-6)
- Formalize failed_layers variable handoff between steps (P-5)
- Add Acceptance Auditor skip note for no-spec mode (P-4)
- Guard false-clean when review layer failed (P-7)
- Reword patch recommendation to avoid auto-fix solicitation (P-3)
- Update SKILL.md description to reflect new capabilities (P-2)

    - When multiple phrases match, prefer the most specific match (e.g., "branch diff" over bare "diff").

-     - **Exactly one `review` story:** Suggest it: "I found story {story-id} in `review` status. Would you like to review its changes? [Y] Yes / [N] No, let me choose". If confirmed, use the story context to determine the diff source (branch name derived from story slug, or uncommitted changes). If declined, fall through to instruction 2.
