Subject: [PATCH] fix: add cross-platform Node.js launcher for Windows
 CMD/PowerShell support

The `./start-automaker.sh` script doesn't work when invoked from Windows
CMD or PowerShell because:
1. The `./` prefix is Unix-style path notation
2. Windows shells don't execute .sh files directly

This adds a Node.js launcher (`start-automaker.mjs`) that:
- Detects the platform and finds bash (Git Bash, MSYS2, Cygwin, or WSL)
- Converts Windows paths to Unix-style for bash compatibility
- Passes all arguments through to the original bash script
- Provides helpful error messages if bash isn't found

The npm scripts now use `node start-automaker.mjs` which works on all
platforms while preserving the full functionality of the bash TUI launcher.
