Continue this Chat - Enhancement Request

I would like to suggest a new feature, "Continue this chat". This would solve multiple issues, including bumping into the chat conversation size liminiation and having to start over without context available in the new chat (because the old chat is dead and you cannot generate a summary). This would also address this feature request: https://github.com/microsoft/copilot-for-eclipse/issues/57

The "Continue this chat" feature would:

• generate a summary of the current chat
• create a new chat with a new title showing it's a continuation (like adding a "part 2" or "part N" to the end of the name)
• post in the summary of the previous chat to let Copilot know this is a continutation and provide it the proper context
• preserve all your settings (file attachments, Agent choice, Model choice, configured tools, etc).

ChatGPT suggests something like this for the continuation summary:

Conversation Continuation Context

• What we’re working on
• Key decisions so far
• Assumptions
• Open TODOs
• What should not be re-explained

No implementation files or tests are named in the issue. Start by reviewing the Eclipse plugin’s existing chat flow and linked issue #57, then identify how chats, summaries, titles, settings, attachments, agents, models, and tools are represented. Done means a continuation creates a new titled chat with prior context and preserved settings.
