feat: /plan-design-review + /qa-design-review skills (v0.5.0) (#102)

* feat: add {{DESIGN_METHODOLOGY}} resolver and register design review skills

Add generateDesignMethodology() to gen-skill-docs.ts with 10-category, 80-item
design audit checklist. Register plan-design-review and qa-design-review templates
in findTemplates(). Add both skills to skill-check.ts SKILL_FILES. Add command
and snapshot flag validation tests for both skills in skill-validation.test.ts.

* feat: add /plan-design-review and /qa-design-review skills

/plan-design-review: report-only designer audit with letter grades, AI slop
scoring, structured first impression, design system extraction, DESIGN.md
inference and export offer. Never modifies code.

/qa-design-review: same audit, then iterative fix loop with style(design):
commits, CSS-safe WTF heuristic, before/after screenshots, final re-audit.

* chore: bump version and changelog (v0.5.0)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* docs: update README, ARCHITECTURE for design review skills (v0.5.0)

- Update skill count to 11, add /plan-design-review and /qa-design-review
  to skill table, install/uninstall commands, and demo walkthrough
- Add narrative sections: "senior designer mode" and "designer who codes mode"
  with compelling examples showing AI Slop detection and design system inference
- Add {{DESIGN_METHODOLOGY}} to ARCHITECTURE.md placeholder table
- Extend demo to show full plan→eng→review→ship→qa→design-review pipeline

* chore: regenerate design review SKILL.md files after merge from main

Picks up BASE_BRANCH_DETECT resolver and updated contributor mode from main.

* feat: add /design-consultation skill — design consultant that creates DESIGN.md

6-phase consultant flow: product context → competitive research (WebSearch) →
complete coherent proposal → drill-downs on demand → font+color preview page →
write DESIGN.md + update CLAUDE.md. Opinionated recommendations grounded in
product context, not menu-driven forms.

* test: add E2E tests for design skill family (7 tests + LLM quality judge)

Tests 1-4: /design-consultation (core flow, research integration, existing
DESIGN.md handling, font+color preview generation).
Tests 5-6: /plan-design-review (audit report, DESIGN.md export).
Test 7: /qa-design-review (audit + fix loop).
LLM judge validates font blacklist compliance, coherence, and AI slop avoidance.
Also adds plan-design-review + qa-design-review to ALL_SKILLS test array.

* chore: mark /design-consultation as shipped in TODOS.md

Renamed from /setup-design-md to reflect the consultant approach.
