Classroom: OneDrive/cloud sync destroys git repos #28
Description
Parent issue: #24
Problem
A professor found that OneDrive causes severe performance degradation with git repos due to file synchronization. This affects Windows students who default to storing everything in their OneDrive folder. The problem manifests as slow git operations, corrupted index files, and phantom changes.

Proposed changes
- Add a warning in setup documentation: clone repos outside of OneDrive, iCloud, Google Drive, or Dropbox-synced folders
- This primarily affects the local Docker Desktop workflow (not Codespaces, where files live in the cloud VM)
