feat: add Windows venv wrappers support (#768)

Windows lacks built-in shell aliases like Unix's bashrc, so Safety uses .bat wrappers in a scripts directory prepended to PATH. However, when users activate a virtual environment, the venv's Scripts directory gets prepended to PATH, causing commands like 'pip' to bypass our Safety wrappers entirely. This implementation solves the issue by adding doskey aliases for CMD (via AutoRun registry) and PowerShell functions (via profile scripts), ensuring Safety's command interception works regardless of PATH order changes during venv activation.
