Subject: [PATCH 2/2] chore(deps): move rust-numpy to 0.30 in lockstep with
 pyo3 0.30

rust-numpy 0.N requires pyo3 ^0.N, so the pyo3-only bump cannot compile
(two pyo3-ffi versions would both link libpython). Fold the numpy 0.30
bump in here, refresh the Cargo.toml comment (pyo3 0.30 spans Python
3.9-3.15, MSRV 1.85 = our rust-version), and add a Dependabot group so
the pair arrives as one PR in future.
