//! End-to-end integration test for `net-mesh typegen generate --language ts
//! --from-snapshot`. Fully offline: it writes a `TypegenSnapshot` JSON
//! fixture, drives the `net-mesh` binary as a subprocess, and asserts the
//! generated TypeScript module / index / metadata files have the expected
//! shape. The live-discovery path (which needs a running mesh) is covered
//! separately; the snapshot path is the deterministic CI surface.
