fix: Windows test compatibility for worktree, snapshot, and history paths

- Replace `mkdir -p` shell calls with `mkdirSync({ recursive: true })`
  in worktree tests (cmd.exe doesn't support -p)
- Normalize path assertions in provider-snapshot-manager tests for
  Windows drive-letter resolved paths
- Add `:` to Claude history path sanitization so Windows drive letters
  (C:\) don't produce invalid directory names
