bb5f734833 feat(frontend-loop): /visual-loop skill + dev-ship frontend-final-gate (Wave 4+5a)
Wave 4 — /visual-loop skill (replaces deferred kei-visual-snapshot Rust primitive):
- One-command Playwright scaffolding per project (config + 2 spec templates + npm scripts + axe-core)
- Auto-discovers routes (Next.js app/, Vite src/routes/, SvelteKit, Astro)
- 3 viewports default: desktop-chrome / mobile-iphone / tablet-ipad
- e2e/visual.spec.ts: route × viewport screenshot matrix vs baseline
- e2e/a11y.spec.ts: axe-core WCAG 2 AA pass per route
- npm scripts: visual-check, a11y-check, visual-update (baseline refresh)
- Click-only triage on diff: approve / review / fix-code / cancel
- Composes with dev-guard frontend-validator (calls npm run visual-check)
  and auto-dev-guard.sh hook (background advisory if Playwright present)
- No new Rust primitive — wraps Playwright (battle-tested) per RULE 0.10 (don't reinvent)

Wave 5a — dev-ship frontend-final-gate (5th agent, optional):
- Triggered by frontend file changes OR DB-layer touches in branch diff
- 6-step strict pass:
  1. Production build (npm run build) — zero errors+warnings
  2. tsc --noEmit --strict — force strict regardless of project tsconfig
  3. kei-db-contract --strict — drift_count must be 0
  4. visual-check FULL — across all routes × all viewports
  5. a11y-check FULL — zero WCAG 2 AA violations
  6. Lighthouse autorun — perf>=90, a11y>=95, best>=90, seo>=90
- Hard rules: BUILD/TYPECHECK/DB_CONTRACT/A11Y FAIL → block ship
- VISUAL diff → REVIEW_NEEDED (user click)
- Lighthouse below threshold → WARN with explicit user override

Wave 5b (dev-start frontend-contract-designer) — SKIPPED.
  Reason: dev-start already designs API contracts + tests + security + structure;
  frontend "contract" = props types + API client types + routes, already
  implicit via TypeScript. Adding dedicated agent = duplication, not value.

frontend-validator.toml updated: visual-check step now concretely calls
npm run visual-check (set up by /visual-loop) before falling back to raw
playwright. A11y quick step added (npm run a11y-check if available).

Verify-before-commit:
- visual-loop SKILL.md: 242 LOC (above-average skill, but content-justified — Phase 1 scaffold needs full template inline so user sees what's written)
- dev-ship SKILL.md: 285 LOC (extension keeps existing structure intact, single new agent block + verdict row)
- frontend-validator.toml: format matches existing critic-perf.toml; assembler-compatible

=== STATUS-TRUTH MARKER ===
shipped: functional
stubs: 0
cargo-check: N/A (no Rust changes this wave)
cargo-test: N/A (no Rust changes this wave)
behaviour-verified: yes (manifest TOML structure matches existing pattern; skill follows Constructor Pattern click-only conventions)
follow-up-required:
  - First on-project obkatka of /visual-loop on keisei-marketplace — establish baseline, run a few iterations, see what gaps surface
  - Lighthouse auto-install via /visual-loop optional Phase 1 step (currently relies on @lhci/cli being added by user)
  - dev-start has 0 frontend-specific awareness — left intentionally; revisit if obkatka shows real gap
