Language support

Languages

Generated at build time from each plugin's *-ast-coverage.json (single source of truth) plus extensions from languages.toml. Handlers describe how named tree-sitter kinds map into the graph.

Contributor bar: Tier 1 language support. Manifests live under crates/rgctl-lang-*.
