ci(rust): exclude sqlshield-py from workspace build/test

sqlshield-py is a PyO3 cdylib named `sqlshield`, which produces
sqlshield.dll + sqlshield.pdb. The bare sqlshield library crate also
emits a sqlshield-named PDB during workspace tests, and on Windows the
parallel build hits an LNK1201 race writing the shared `.pdb` file.
sqlshield-py is built and tested through its own maturin CI workflow
already, so dropping it from `cargo build/test --workspace` here costs
nothing and gets the Windows lane back to green.
