test: add e2e test for negative input globs in subpackages

Demonstrates a bug where negative input globs (like !dist/**) are
matched against workspace-relative paths instead of package-relative
paths, causing exclusions to fail for subpackages. The snapshot
captures the buggy behavior (cache miss instead of expected hit).
