apk add without --no-cache tends to leave package index/cache behind, which can slow CI and increase container layer size. Consider using apk add --no-cache gsl-dev; similarly consider cleaning yum metadata after install (e.g., yum clean all) if these images persist across steps.

Suggested change

	apk add gsl-dev # musllinux (Alpine)
	else
	yum install -y gsl-devel # manylinux (CentOS/RHEL)
	apk add --no-cache gsl-dev # musllinux (Alpine)
	else
	yum install -y gsl-devel && yum clean all # manylinux (CentOS/RHEL)

PR title mentions "allow underscores in model names", but this PR’s squashed diff only touches .gitignore and tools/wheels/* (plus the GSL install here). Either the title should be updated to reflect the actual changes, or the missing change should be included in this PR/linked to the correct stacked PR.
