Zig never analyzes the body of a function that is never called, so refAllDecls alone lets broken wrappers pass the test suite. The new test gives every public wrapper a real call site behind a never-taken branch. It immediately caught three more latent bugs: getMtime wrapped a time_t return value as a status code, Query.getDatabase assigned null to a non-optional field instead of returning null, and countMessages matched a nonexistent .xapian_error status.
