feat: improved conversation management

[cwallace]

Problem:
I start several dozen conversations, sometimes over a hundred per day. When I need to clean up my chats, I have two options:

1. Click to More, Delete, Confirm on each old chat. That is 36 clicks to delete a dozen conversations.
2. Go to settings and delete all chats. However, this also deletes archived chats, which I may want to keep.

Proposed solution:
Multi-conversation management: Implement the ability to select multiple conversations at once and then perform batch actions such as tagging, archiving, or deleting them.

Archived chat handling: Ensure that deleting all chats does not include archived messages. If this is intentional, then adding the ability to "lock" conversations to prevent them from being deleted would be a valuable feature.

Example workflow:

1. User clicks a "select" button at the top of the conversation list.
2. User selects multiple conversations from the list or click "select all".
3. User can then choose to archive, tag, or delete the selected conversations in a single action.

Benefit:
This feature would greatly improve the user experience for users who manage a large number of conversations on a daily basis. It would provide a more efficient way to organize and maintain their chat history, while ensuring that important archived conversations are not accidentally deleted.

Yeah, It would be cool if you could group them up in "folders". LLM Studio has a really nice feature where you can "fork" a conversation. This way a base conversation can work as a starting point.

@AdaptiveStep forking conversation feature has been requested before but I’m struggling to see its utility when conversation branching feature already exists. Am I missing something here? I’d like to hear your opinion!
