Replace Unix-only init.sh with cross-platform init.mjs Node.js script.
Changes:
- Add init.mjs: Cross-platform Node.js implementation of init.sh
- Update package.json: Change dev script from ./init.sh to node init.mjs
- Add tree-kill dependency for reliable cross-platform process termination
Key features of init.mjs:
- Cross-platform port detection (netstat on Windows, lsof on Unix)
- Cross-platform process killing using tree-kill package
- Uses cross-spawn for reliable npm/npx command execution on Windows
- Interactive prompts via Node.js readline module
- Colored terminal output (works on modern Windows terminals)
- Proper cleanup handlers for Ctrl+C/SIGTERM
Bug fix:
- Fixed Playwright browser check to run from apps/app directory where
@playwright/test is actually installed (was silently failing before)
The original init.sh is preserved for backward compatibility.
