Master's new duplication gate flagged 4 clones, all from the website scripts
reusing existing gate patterns by copy. Extracted the shared halves instead of
ignoring:
- scripts/cordis-walk.ts — cordisModuleBody / eventMembers / serviceClasses,
one AST walk consumed by both gen-cordis-catalog and gen-website-api (the
two renderers must agree on WHAT exists; now they structurally do).
- scripts/md-fences.ts — fence extractor with per-gate info-string
classification, consumed by doc-typecheck and verify-website-yaml.
Behavior-neutral: regenerated catalogs and website pages are byte-identical
(--check green), doc-typecheck/yaml block counts unchanged. jscpd now reports
0 clones; full pre-push run 34/34 green.
