1//! The canonical language metadata catalog (0051 §3): ONE in-repo table
2//! mapping file extensions to language names and back. The LSP registry
3//! and the query compiler both consume this — there is no second table.

5/// One language family: canonical name, filename extensions, documented
6/// value aliases (`rs` reads as `rust`).
