Mac Local Dev Setup

I need a streamlined local development workflow for my platform on macOS Monterey. At the moment npm run dev fails because of permission issues inside node_modules, so I can’t preview dashboard and UX tweaks before pushing live.

Here’s the outcome I’m looking for:
• Fix the node_modules permission problem so the project starts cleanly.
• Configure Node.js under NVM and make sure the correct version is selected automatically for the repo.
• Create a “one-liner” (npm run dev or similar) that I can launch from VS Code and immediately view the app at localhost.
• Ensure the GitHub push → auto-deploy pipeline remains unchanged; local work should stay isolated.
• Provide a concise, step-by-step guide (markdown is fine) so I can repeat the setup on any future Mac without guesswork.

Key context:
– macOS Monterey environment.
– I routinely open the project in VS Code.
– NVM is my preferred package manager for Node.

If you’ve solved similar permission or environment issues before, I’d love to hear how quickly you can get this running and what your process looks like.
