Blog reconstruction project

This project keeps full @iconify/json and may require more memory during pnpm install.

1. Use the expected Node runtime via nvmd.
2. Verify runtime and env:
   • pnpm run env:check
3. Install with stable parameters:
   • pnpm run install:stable
   • This script uses nvmd Node directly to run pnpm.cjs.
   • If current Node major is 24+, it auto-falls back to installed Node 22.x in nvmd for install stability.
