Streamline workspace tooling and Windows automation

[112-stack]

Summary

• add an npm workspace root with a cross-platform dev orchestrator so the API and client can start together cleanly
• harden the Windows installer/runner to validate project layout, handle paths with spaces, and warn about leftover Flask stacks
• document the new workflow, expose configurable API base URLs for the client, and guard the server against missing OpenAI configuration

Testing

• node --check server/src/index.js
• node --check tools/dev.mjs

Respect API base URL in chat hook

The chat hook posts to '/api/chat' using the default axios instance, ignoring the configurable API base URL that was added for the other client requests (submitInsightRequest/submitComparisonRequest). If the UI is deployed separately from the Node server and VITE_API_BASE_URL points to the remote API host, insight and comparison requests succeed while chat continues to hit the UI origin and fails (404/CORS). The hook should reuse the configured axios client or prepend the same environment base so remote deployments keep chat functional.
