A string a catalog lacks shows in English. Coverage, key-parity and
per-language count tests and tests of one language's exact wording are
removed; UI wiring tests take their expected text from the catalog.
cargo xtask i18n-report lists the missing strings per language and
always passes; cargo xtask ci runs it first.
* CI: dev builds keep line tables only
* CI: one integration-test binary per crate
* CI: xtask runs tests with nextest, doctests apart, --keep-going on clippy and wasm
cargo xtask test runs the workspace tests (--lib --bins --tests) with cargo-nextest when it is installed, else cargo test, then the doctests. cargo xtask ci uses the same two steps.
* CI: docs name cargo xtask test
* CI: agent guides name the moved fuzz test
* CI: tests added on main join their crate's test binary
