Fusion - the Fusion 360 Bridge

//! The verb catalog is the contract both the Python bridge and this crate must serve
//! identically. It is frozen in `contracts/describe.json` (regenerated ONLY from
//! describe.py) and loaded here so the Rust router can assert it serves every verb the
//! catalog names, with the same argument names.
