Introduce RSC "live reload."

[peterp]

This PR introduces a development server with "live reload" functionality to the RSC parts of Redwood. Live reload enables developers to see changes immediately after saving a file, without needing to perform any additional actions.

The primary goal of this PR is to enhance the development experience. While live reload is a basic implementation of the "do something, see something" paradigm, it offers significant improvements to developer efficiency with minimal effort.

Here's a loom: https://www.loom.com/share/51463c3f6f1b40c5b8ee79d599f673d7?from_recorder=1&focus_title=1

How does it work?
We use chokidar to monitor the user's workspace for file changes. When a file change is detected, the following steps are executed:

1. The existing process is terminated.
2. The old code is deleted.
3. The code is rebuilt.
4. The development server is restarted.
5. An event is sent to the frontend to reload the page.
6. The frontend receives the event and refreshes the page.

This process allows developers to see the impact of their changes immediately without needing to manually rebuild and restart the web server.

Next steps: I plan to focus on speed improvements and then implement Hot Module Replacement (HMR).

Test it yourself:

cd ~/examples/
cp -R ~/gh/redwoodjs/redwood/__fixtures__/test-project-rsc-kitchen-sink .
cd test-project-rsc-kitchen-sink
yarn install
yarn rwfw project:sync
yarn rw-dev-rsc

This is a command that will be executed by the Redwood CLI.

I'm not sure if hard coding this port is the correct approach, but could be OK for right now?

Yeah, good enough for now! 🙂
