feat: interactive /plan-design-review + CEO invokes designer + 100% coverage (v0.6.4) (#149)

* refactor: rename qa-design-review → design-review

The "qa-" prefix was confusing — this is the live-site design audit with
fix loop, not a QA-only report. Rename directory and update all references
across docs, tests, scripts, and skill templates.

* feat: interactive /plan-design-review + CEO invokes designer

Rewrite /plan-design-review from report-only grading to an interactive
plan-fixer that rates each design dimension 0-10, explains what a 10
looks like, and edits the plan to get there. Parallel structure with
/plan-ceo-review and /plan-eng-review — one issue = one AskUserQuestion.

CEO review now detects UI scope and invokes the designer perspective
when the plan has frontend/UX work, so you get design review
automatically when it matters.

* test: validation + touchfile entries for 100% coverage

Add design-consultation to command/snapshot flag validation. Add 4
skills to contributor mode validation (plan-design-review,
design-review, design-consultation, document-release). Add 2 templates
to hardcoded branch check. Register touchfile entries for 10 new
LLM-judge tests and 1 new E2E test.

* test: LLM-judge for 10 skills + gstack-upgrade E2E

Add LLM-judge quality evals for all uncovered skills using a DRY
runWorkflowJudge helper with section marker guards. Add real E2E
test for gstack-upgrade using mock git remote (replaces test.todo).
Add plan-edit assertion to plan-design-review E2E.

14/15 skills now at full coverage. setup-browser-cookies remains
deferred (needs real browser).

* docs: add bisect commit style to CLAUDE.md

All commits should be single logical changes, split before pushing.

 ## What's new and why it matters
 
-**Design is at the heart.** `/design-consultation` doesn't just pick fonts. It researches what's out there in your space, proposes safe choices AND creative risks, generates realistic mockups of your actual product, and writes `DESIGN.md` — and then `/qa-design-review` and `/plan-eng-review` read what you chose. Design decisions flow through the whole system.

 **`/qa` was a massive unlock.** It let me go from 6 to 12 parallel workers. Claude Code saying *"I SEE THE ISSUE"* and then actually fixing it, generating a regression test, and verifying the fix — that changed how I work. The agent has eyes now.
