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.

 # Changelog
 
+## [0.11.3.0] - 2026-03-23 — Design Outside Voices
+
+### Added
+
+- **Every design review now gets a second opinion.** `/plan-design-review`, `/design-review`, and `/design-consultation` dispatch both Codex (OpenAI) and a fresh Claude subagent in parallel to independently evaluate your design — then synthesize findings with a litmus scorecard showing where they agree and disagree. Cross-model agreement = high confidence; disagreement = investigate.
+- **OpenAI's design hard rules baked in.** 7 hard rejection criteria, 7 litmus checks, and a landing-page vs app-UI classifier from OpenAI's "Designing Delightful Frontends" framework — merged with gstack's existing 10-item AI slop blacklist. Your design gets evaluated against the same rules OpenAI recommends for their own models.
+- **Codex design voice in every PR.** The lightweight design review that runs in `/ship` and `/review` now includes a Codex design check when frontend files change — automatic, no opt-in needed.
+- **Outside voices in /office-hours brainstorming.** After wireframe sketches, you can now get Codex + Claude subagent design perspectives on your approaches before committing to a direction.
+- **AI slop blacklist extracted as shared constant.** The 10 anti-patterns (purple gradients, 3-column icon grids, centered everything, etc.) are now defined once and shared across all design skills. Easier to maintain, impossible to drift.
