The production build renders thousands of modules and exceeds V8's
default heap ceiling, so `npm run build` fails with a JavaScript
heap out-of-memory error during "rendering chunks". Set
NODE_OPTIONS=--max-old-space-size=8192 on the Vite build step via
cross-env (kept portable for Windows), so a fresh clone builds
without any manual environment setup. Document the matching Docker
memory requirement in DOCKER.md, since the container build hits the
same limit when the Docker VM has too little RAM.
Correct the "Welcome" heading typo and reword "Index Suggestions"
in the feature list. The intro now lists all six exportable SQL
dialects (adding Oracle and SQL Server) so it matches the
Supported Databases section. Add the port 3000 dev-server URL to
the local setup instructions, and switch the Docker Compose
commands in README and DOCKER.md from the deprecated V1
"docker-compose" to the current V2 "docker compose" syntax.
