fix: Windows test compat — shell quoting, line endings, binary names

- Replace single-quoted git commit messages in worktree tests with
  double quotes (cmd.exe doesn't treat single quotes as delimiters)
- Trim stdout in spawn tests to handle \r\n vs \n
- Use nonexistent binary name in executable test not-found case
