chore: add .nvmrc for Node version consistency across environments

[aniruddhaadak80]

📈 Why is this useful?

Currently, developers have to manually parse package.json to know which Node version to use locally, and CI/CD tools might default to older versions.

This PR adds an .nvmrc file targeting Node 20 (the current active LTS) to automatically standardize the development environment. When contributors run
vm use, or when deployment bots (Netlify/Vercel) build the application, they will seamlessly pick up the intended Node version, preventing runtime and module resolution bugs.

🛠️ Key Changes

• ✅ Added .nvmrc mapped to Node 20.

[Copilot]

.nvmrc pins Node 20, but the repo currently declares Node 24.x in package.json engines.node and CI workflows use node-version: '24'. This mismatch will cause local/dev tooling to use a different Node than CI/production; align .nvmrc to the same version (or update engines/CI together if 20 is intended).
