Integrity files collide when generating node modules

[tobni]

Describe the bug
Newer versions of package managers generate integrity files (e.g .package-lock.json, notice the leading .).
The current strategy of merging node_modules installations across workspaces will collide in these integrity files,
because the digests were generated from subsets, and but the integrity file is in the same location on disk.
