fix: skip mkdir when C3 parent dir already exists

[AiAlchemist0]

Fixes #5448

create-cloudflare always mkdirSyncs the parent of the project path. On Windows that parent can be a drive root (E:\), which already exists and throws EPERM. Skip mkdir when the parent is already there.

• Tests
  • Tests included/updated
• Public documentation
  • Documentation not necessary because: this is internal mkdir behavior; no user-facing docs or CLI flag changed.

I used an assistant on the edit.
