Lib.rs

Tree-sitter extractors split into two layers:

• lang — pure language extraction (decls, imports, calls, type bindings). One module per supported language.
• framework — framework-specific overlays that extend a language (Axum routes for Rust, FastAPI/Flask routes for Python, the entire Rails DSL for Ruby). Frameworks are called by their language module when a known framework call shape appears in the AST.

Adding a new framework: create framework/<name>.rs, expose detector functions, and call them from the relevant lang/<x>.rs walk.
