fix(test): 消掉 Windows cmdline 用例里的 SyntaxWarning

[leeguooooo]

#38 合入时带进来的两条断言用了非法转义序列：

• "C:\Python\python.exe" → \P
• "C:\Windows\explorer.exe" → \W

Python 3.12+ 每次收集测试都会打 SyntaxWarning，未来版本里会直接变 SyntaxError。改成 raw string / 显式转义，断言内容和覆盖不变。

验证：compile() 扫全量 src+tests，syntax warnings 从 2 降到 0；tests/test_daemon.py 65 passed。

Summary by CodeRabbit

• Tests
  • Updated Windows daemon-identity test fixtures to accurately reflect expected command output.
  • Corrected escaping in mocked process results to improve test reliability.
