Description

Is your feature request related to a problem? Please describe. If you are editing text or components, idyll should be able to intelligently re-render a new AST as opposed to reloading the entire page.

Describe the solution you'd like Instead of using "live reload", we should just send a new AST to the client and have it rerender that.

Research direction
This feature request proposes replacing the current live reload mechanism with a smarter approach that sends only the new AST to the client for re rendering. To implement, first examine how the current live reload works in the Idyll build pipeline (likely in webpack config or custom server). Identify where the AST is generated and sent to the client (e.g., via WebSocket or HTTP). Research how to intercept AST changes and send incremental updates. Look at the client side rendering code to see how to update the page without full reload. The main files to investigate are in the 'src/' directory, particularly any server or build related modules. No existing PRs or comments provide further guidance.
