feat(highlight): migrate to tree-house with Helix queries

Replace tree-sitter-highlight dep with tree-house crate from Helix
editor. Add ropey dependency required by tree-house.

Reorganize query files from Helix's runtime/queries/ for all 14
supported languages:
- bash, c, css, go, html, javascript, json, markdown, nix, python,
  rust, toml, typescript, yaml
- Include ecma, _javascript, _typescript base dirs for JS/TS inheritance
- Copy highlights.scm, injections.scm, locals.scm where available

This commit establishes the foundation; highlight.rs implementation
will follow in subsequent commits.
