fix: add comprehensive Windows support with minimal changes

- shell_tools.py: Replace os.uname() with platform.system(), fix Unix path handling, add proper Windows command parsing
- deploy.py: Replace Unix command substitution with cross-platform subprocess calls, handle Windows authentication
- mcp.py: Add Windows-aware command parsing, conditional locale variables, NPX variant detection

All changes maintain full backward compatibility for Unix/Linux/macOS.
