feat: design outside voices — cross-model design critique (v0.11.3.0) (#347)

* feat(gen-skill-docs): add design outside voices + hard rules resolvers

Add generateDesignOutsideVoices() — parallel Codex + Claude subagent
dispatch for cross-model design critique with litmus scorecard synthesis.
Branches per skillName (plan-design-review, design-review, design-consultation)
with task-specific reasoning effort (high for analytical, medium for creative).

Add generateDesignHardRules() — OpenAI Frontend Skill hard rules + gstack
AI slop blacklist unified into one shared block with classifier step
(landing page vs app UI vs hybrid).

Extract AI_SLOP_BLACKLIST constant from inline prose in generateDesignMethodology()
for DRY. Extend generateDesignReviewLite() with lightweight Codex block.
Extend generateDesignSketch() with outside voices opt-in after wireframe.

* feat(design skills): add outside voices + hard rules to all design templates

Insert {{DESIGN_OUTSIDE_VOICES}} in plan-design-review (between Step 0D
and Pass 1), design-review (between Phase 6 and Phase 7), and
design-consultation (between Phase 2 and Phase 3).

Insert {{DESIGN_HARD_RULES}} in plan-design-review Pass 4 and design-review
Phase 3 checklist.

DESIGN_REVIEW_LITE in /ship and /review now includes a Codex design voice
block with litmus checks.

DESIGN_SKETCH in /office-hours now includes outside voices opt-in after
wireframe approval.

Regenerated all SKILL.md files (both Claude and Codex hosts).

* test: add resolver tests + touchfiles for design outside voices

Add 18 test cases across 4 new describe blocks:
- DESIGN_OUTSIDE_VOICES: host guard, skillName branching, reasoning effort
- DESIGN_HARD_RULES: classifier, 3 rule sets, slop blacklist, OpenAI criteria
- DESIGN_SKETCH extended: outside voices step, original wireframe preserved
- DESIGN_REVIEW_LITE extended: Codex block, codex host exclusion

Update touchfiles: add scripts/gen-skill-docs.ts to design skill E2E
test dependencies for accurate diff-based test selection.

* chore: bump version and changelog (v0.11.3.0)

Design outside voices — parallel Codex + Claude subagent for cross-model
design critique with litmus scorecard synthesis. OpenAI hard rules + gstack
slop blacklist unified. Classifier for landing page vs app UI.

* fix: generate .agents/ on demand in tests (not checked in since v0.11.2.0)

.agents/ is gitignored since v0.11.2.0 — tests that read Codex-host
SKILL.md files now generate them on demand via `bun run gen-skill-docs.ts
--host codex` before reading. Fixes test failures on fresh clones.

 Shipped as v0.5.0 on main. Includes `/plan-design-review` (report-only design audit), `/qa-design-review` (audit + fix loop), and `/design-consultation` (interactive DESIGN.md creation). `{{DESIGN_METHODOLOGY}}` resolver provides shared 80-item design audit checklist.
 
+### Design outside voices in /plan-eng-review
+
+**What:** Extend the parallel dual-voice pattern (Codex + Claude subagent) to /plan-eng-review's architecture review section.
+
+**Why:** The design beachhead (v0.11.3.0) proves cross-model consensus works for subjective reviews. Architecture reviews have similar subjectivity in tradeoff decisions.
+
+**Context:** Depends on learnings from the design beachhead. If the litmus scorecard format proves useful, adapt it for architecture dimensions (coupling, scaling, reversibility).
+
+**Effort:** S
+**Priority:** P3
+**Depends on:** Design outside voices shipped (v0.11.3.0)
+
+### Outside voices in /qa visual regression detection
+
+**What:** Add Codex design voice to /qa for detecting visual regressions during bug-fix verification.
+
+**Why:** When fixing bugs, the fix can introduce visual regressions that code-level checks miss. Codex could flag "the fix broke the responsive layout" during re-test.
+
+**Context:** Depends on /qa having design awareness. Currently /qa focuses on functional testing.
+
+**Effort:** M
+**Priority:** P3
+**Depends on:** Design outside voices shipped (v0.11.3.0)
