fix: remove Windows symlink workaround for git clone (#299)

- The installer uses copyRecursiveSync which copies files,
  not symlinks, so git clone without core.symlinks works fine
- The previous Windows-specific git -c core.symlinks=true clone
  required admin privileges, causing install failures
- This fix allows non-admin Windows users to install

Fixes #286
