Create a JBrowse plugin for the WebUI

[carolinebridge]

It could be useful to embed the WebUI into a JBrowse plugin so a user could have their assistant open side-by-side to their JBrowse session while asking it questions. Some thoughts:

• instead of providing a link, a button could be provided that navigates the user on-click to their location in-session without reloading the page, and this is an "undo"able action
• the plugin could automatically link into the user's session so the user wouldn't have to provide a location for their JBrowse configuration data
• the user would still have to provide an LLM they'd like to use and their token for using it in the interface itself, or in their JBrowse configuration file with the plugin information
