simplify cargo test dependencies

Remove unused macro dependencies and circular test dependencies, refresh Hakari,
and inherit the existing CI profile overrides. Preserve test inventories and
per-crate Nix cache boundaries; regenerate CI metadata and document local results.

Validation: 631-test direct local pair 6m52s -> 6m13s; check then tests
10m31s -> 7m12s. Selected Nix suite passed 1,633 runtime tests, 43 doctests
and static checks. FeynKit graph/cache boundaries evaluated; no remote run.
