Marketplace names that differ only in letter case are now rejected

Two marketplaces whose names differ only in capitalisation now collide loudly instead of silently.

What

Publishing a marketplace configured through settings now clears stale directories that differ only in capitalisation, and fails if the name case-folds onto a marketplace already registered next to it. This avoids two marketplaces colliding on filesystems that ignore case.

Details
  • Applies to every settings-sourced marketplace publish, with no flag.
Evidence

marketplace name case-folds onto a registered sibling

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
