chore(core): first working version of extension loading

[andypf]

Summary

This update introduces a new Extension Loading Mechanism powered by npm, ensuring seamless integration of extensions into the application. Extensions are loaded into a temporary folder via npm, moved to node_modules, and accompanied by auto-generated import files for both client-side and server-side use—forming the backbone of this system.

Additionally, the server architecture has been streamlined by integrating Vite directly into Fastify using the @fastify/vite package. This allows for a single-server setup in development and production, eliminating the need for a standalone Vite server.
