skill: drop quality tiers, keep the real brand-craft guardrails

Codex's craft/brand pass introduced fast/ship/showpiece "quality bars"
plus brand-specific build gates, asset ledgers, sub-agent review, and
self-graded fallback labels. In practice those tiers became escape
hatches rather than craft pressure: the final output should always be
10/10, and the real decision points are splashiness and maximalism, not
quality.

Removed:
- All quality-bar / showpiece / fast / ship framing in shape.md and craft.md
- Standalone Brand Direction (#4) and Asset Requirements (#10) sections
  in shape's brief; renumbered back to 1-10
- The Brand hard rules section in brand.md (folded its real prohibitions
  into the existing Imagery and Brand bans sections)
- Brand-specific build-gate item, mock-fidelity bullet, production-bar
  bullet, present-step bullet in craft.md
- Asset ledger ceremony in craft Step 4
- Review-only sub-agents and "self-reviewed fallback, not independently
  validated" machinery in craft.md and polish.md
- The For brand surfaces, assess hard failures subsection in polish.md
  and the brand checklist row
- tests/brand-showpiece-reference.test.mjs (and its package.json wiring)

Kept (the real nuggets):
- Asset-substitution prohibition: image-led briefs ship real/generated
  assets or canvas/SVG/WebGL, not generic CSS panels, cards, bullets,
  or copy
- Repeated tiny uppercase tracked kicker labels as a brand ban
- Detector/QA output is defect evidence only, never proof of quality
- "What visual assets are real content here?" discovery question
- Inspect each major section individually for brand and long-form work
- repeated-section-kickers detection rule + fixture
- CLI improvements (JSON to stdout, -json/-fast aliases, severity field)
- critique.md: npx impeccable detect --json fix

Harness output dirs refreshed via bun run build. Full test suite (186)
passes.
