feat(review): generate review/design-checklist.md from the catalog

review/design-checklist.md was hand-written and its own header admitted it
drifted from DESIGN_METHODOLOGY category 9. It is now rendered by
scripts/resolvers/design-checklist.ts from lib/design-catalog.ts: category 1
lists every grep-detectable slop entry plus the legacy blacklist lines,
sorted HIGH/MEDIUM/LOW, each with its heuristic and, where the detector knows
the rule, its bracketed id (27 items, up from 6). The font blacklist renders
from BANNED_FONTS. Categories 2-5, Instructions, Classification, Output
Format, and Suppressions keep their prose. Title and slop heading are
unchanged (test/skill-e2e-review.test.ts and hosts/opencode.ts key on them).

gen-skill-docs writes the file for the Claude host only (a Claude-side
runtime asset; other hosts copy or inline the render), honors --out-dir, and
reports STALE/FRESH under --dry-run like sections do.
test/design-checklist-sync.test.ts pins committed == generated, the
host/out-dir scoping, and the dry-run freshness line.
