Allow developers to write plugins that would show in the workbench. The goal is to let developers create tools similarly to what we provide out of the box, like the endpoints page.

Plugins can add a new tab to the top or bottom panel that could open a side panel when clicking. Maybe we want to have a chatbot to create stuff in Motia that we could interact with in the workbench.

Another use case would be a internal tool for a project so developers can easily test their motia backend with sets of tests or workflows, so they could just run them and watch, the view could be similar to endpoints page where they can list all the test-cases they created and when clicking in one, it would open a sidepanel with the play button and when clicking on play they could watch it running and the checks it made.

Once we start working on this, more features will need to be implemented to support wider plugins
