Fix blank page: set VSCODE_DEV=1 for dev workbench template

Summary

The site at https://ide.orcest.ai/ renders a blank page because the server expects bundled assets (workbench.css, nls.messages.js) that don't exist. These are only produced by the full packaging pipeline (gulp vscode-web-min), but the Dockerfile uses npm run compile which only compiles TypeScript to out/.

Setting VSCODE_DEV=1 makes isBuilt return false, which switches the server to use workbench-dev.html — a template that loads CSS dynamically via import maps instead of requiring a pre-bundled CSS file.

Review & Testing Checklist for Human

• Audit side effects of VSCODE_DEV=1 in production. This flag controls isBuilt which is checked in many places beyond just the HTML template selection — it affects static file caching (ETAG vs immutable), extension loading, product.overrides.json loading, settings sync, and likely other behaviors. Grep for isBuilt and VSCODE_DEV across the codebase to assess whether any of these side effects are unacceptable for your deployment.
• Verify the page actually loads after deploy. This fix is inferred from code analysis only — it has NOT been tested in the Render.com environment. After merge, confirm https://ide.orcest.ai/ renders the VS Code workbench (not a blank page or error).
• Check CSS loading performance. The dev template uses ICSSDevelopmentService which runs ripgrep at server startup to discover all .css files. Verify this doesn't cause excessive startup latency or fail silently in the Docker container.
• Consider replacing with a proper production build long-term. This is a workaround. The correct fix is to use the full VS Code web packaging pipeline to produce bundled assets, which would allow running without VSCODE_DEV=1.
