Chameleon

Added

• NestJS controller→module co-change advisory. A new *.controller.ts added
  without a *.module.ts companion in the same change-set now surfaces a turn-end
  advisory: a controller that is never registered in a @Module's
  controllers: [...] array is never routed. This is the TypeScript sibling of the
  Rails controller→route and Django model→migration co-change rules. It is
  framework-gated — it fires only where a package.json declares @nestjs, so an
  Angular (*.module.ts) or routing-controllers / Express (*.controller.ts)
  repo that merely shares the filename suffix never arms it. Advisory, new-file-
  only, honors # chameleon-ignore.

Changed

• docs/language-support-matrix.md revalidated against the code and its parity
  gaps re-audited. Every file:line reference was re-derived against the current
  source, the At-a-glance tallies recomputed from the tables, and all remaining
  ⚠️/❌ cells re-confirmed as settled language-specific exceptions (each either
  structurally impossible or false-positive-inducing to "close") — except the
  NestJS companion pairing added above, which moves TypeScript companion-co-change
  to full parity (130 all-three-✅ capabilities).
