add style to chat after chat already started

new user testing out spiral v3. can see how it integrates ideas from the previous version and adds other ideas for a full fledged writing copilot

A few things that jump out:
1. no central space for drafts. what if i’m not in a specific chat and want to work on something? there doesn’t seem to be a good way to manage drafts. as a writer, my work starts and stops with a document page, not a chat

2. as a new user i’m trying things out. i started what turned out to be a very productive session and then created some styles. now i find i can’t add the style to the current chat nor are drafts shared between chats
