Also clean up userland cargo.toml config and import surface area
This introduces engine_import_path, a necessary parameter for codegen — Previously we hard-coded pax_engine via codegen; this breaks whenpax_kit is the entrypoint instead. We need to support both, so this parameterizes that symbol, allowing pax-std and pax-designer to override. (the two canonical crates where we use pax_engine instead of use pax_kit)

./paxhelper script.
