* CI: line-table debug info for dev builds, none for dependencies * CI: one integration-test binary per crate * CI: nextest with doctests, test build without examples, one wasm check * CI: the interface audit reports missing catalog entries instead of failing * Docs: the interface audit, not CI as a whole, passes with missing catalog entries
