fix: increase Node.js heap size for Netlify builds (#1446)

## Description
- Fix Netlify build failure caused by Node.js running out of heap memory
during Vite
  production build

  ## Problem
  The production build was failing with:
FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out
of memory

The build process consumed ~2GB before crashing, exceeding Node's
default heap limit.

  ## Solution
Added `NODE_OPTIONS="--max_old_space_size=4096"` to `netlify.toml` build
environment,
  increasing the heap limit to 4GB.
