release(claude-design): v0.2.0 — Phase 9 critique-iterate

Version bump plus the docs sync that ships Phase 9.

- .claude-plugin/plugin.json: 0.1.0 -> 0.2.0
- CHANGELOG.md: [0.2.0] entry covering the shared 05-critique-iterate.md
  reference, the eight per-preset hint blocks, export-to-HTML as the input,
  operator-confirmed layer mapping, untrusted-paste rule, operator-attested
  exit, design:critique routing, accessibility deferred to v0.4, the new
  SC4 test and the dual-format SC1 dogfood check.
- README.md: version badge 0.1.0 -> 0.2.0, references badge 13 -> 14,
  trigger count 12 -> 16, a Non-goals bullet routing critique to Phase 9,
  and a v0.2.0 release-history entry.
- CLAUDE.md: Status v0.2.0, nine-phase surface line, Architecture heading,
  and a Scope-fence paragraph stating Phase 9 routes to design:critique
  without duplicating it.

Two corrections of stale claims found while sweeping:
- CLAUDE.md said the hint-block heading letter is (e)/(f); measured across
  all eight presets it is (f) x4 and (g) x4. The letter-free substring
  'Critique-iterate hint' remains the canonical anchor.
- The README badge said 13 references and 12 triggers; ground truth is 14
  and 16.

Historical records left verbatim: the [0.1.0] and [0.1.0-pre] CHANGELOG
entries, the v0.1.0 README release note, and docs/review-2026-06-20.md all
describe what v0.1.0 actually shipped.

Deviation from the plan's pinned check: the plan expects a literal
'## v0.2.0' CHANGELOG heading, but this file has used Keep a Changelog
bracketed headings since v0.1.0. The entry is '## [0.2.0]' to match the
file; no shipped test asserts either form.

No tag, no catalog bump. /trekreview is the release gate and comes next.
