feat: SSR - Reload browser automatically on hot reload

[moshe5745]

Description

Right now we need to manually reload the page to see the change when hot reload triggered

Think that auto-reload the browser is a crucial part of good DX

Requirements

• All CI/CD checks are passing.
• There is no drop in the test coverage percentage.

Thanks for opening this issue @moshe5745 👋

This is a good suggestion and one that would make Dart Frog development feel a bit more like Flutter based development. The first feedback from the team on this is that having some kind of add in being injected when running in Debug mode that would have an open socket back to the Dart Frog server listening for server updates. When an update is received reload the page. This would have the side effect of breaking the current flow that the user is in as there wouldn't be any context saved across the page reload but overall would allow for the Hot Reload functionality.

This feels like something that our proposed Plugin system could be used for as it would be hooking into the build process at certain times. We need to get through that work before implementing this but we can leave this ticket open to try and discuss the implementation specifics and get them documented here before any code get's written.

I don't think we care about "SPA like" state
If we do SSR the client state would be minimal and probably backed up in local storage(like Alpine.js do)

But there is another scenario that could be annoying
When you fill-up a form and it reset on reload
A solution to this could be to save the state of forms in the Dart Frog server
