wheels: avoid vendoring libnvJitLink

[jameslamb]

Description

Noticed while reviewing #1731 and looking through logs... cuopt-cu{12,13} wheels are vendoring a copy of libnvJitLink.so.

$ pydistcheck --inspect ./cuopt_*.whl

That's unnecessary in 2 ways:

• cuopt doesn't directly use nvJitLink (auditwheel is probably picking that up as a transitive dependency coming from cusparse or similar)
• even if it did, it should get a copy from nvidia-nvjitlink-cu{12,13} wheels, not vendor one

This proposes removing that file from cuopt wheels and tightening the wheel-size limits to help prevent things like this from slipping through again.

/ok to test

The .so was dropped from this line in #507, I think because of a misunderstanding of the order things happened in these builds.

auditwheel repair will take a dependency on libnvJitLink.so.13.3.33 and vendor in a library renamed like cuopt_cu13.libs/libnvJitLink-3ba1e744.so.13.3.33.

But this --exclude is matched against the DT_NEEDED entries in the .so files in the wheel, not against the names auditwheel creates afterwards.

So I think we really do want .so here, to avoid accidentally matching an (unlikely, but possible) other file named like libnvJitLink-cuopt-wrapper.so or something.

Changes

Wheel packaging

Layer / File(s)	Summary
Auditwheel library exclusions ci/build_wheel_cuopt.sh, ci/build_wheel_libcuopt.sh	The wheel build scripts exclude libnvJitLink.so and matching suffixes during wheel repair.
Distribution size validation python/cuopt/pyproject.toml	The maximum compressed distribution size changed from 55Mi to 10Mi.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to cb9fd

This change removes an unnecessary vendored library from the wheels and tightens size limits to prevent similar packaging regressions; no actionable merge-blocking risk remains after normal checks and review.
