Chameleon

Documentation: the language and framework support is reframed to match what the
engine actually does. TypeScript/JavaScript, Ruby, and Python are first-class
languages with a framework-agnostic core, learning each repo's conventions
from its own structure so any framework works. The named frameworks are a deeper,
framework-aware layer on top, where conventions are strong: Rails for Ruby, and
Django, DRF, Flask, and FastAPI for Python. No code or behavior change.

Changed

• README, the architecture doc, the install guide, the support matrix, and the
  init/trust/using skills now lead with the languages as the unit of support and
  present the named frameworks as a deeper layer on top of the agnostic core.
• Per-language tooling notes corrected: editing Ruby needs the Prism parser
  because the file is Ruby, not because the repo is Rails.

Fixed

• A stale architecture line that still listed Python as an unsupported language.
