Bomly smoke-test fixture: a virtual Cargo workspace (workspace-only root
Cargo.toml) with two members — crates/api (binary, depends on the
crates/core member plus pinned time 0.1.45 and dev-only
lazy_static 1.4.0) and crates/core (library, time 0.1.45).
Pinned by tag for deterministic goldens — do not update dependencies.
