Subject: feat(assistant): the canvas, a view over the assistant daemon

The socket, the turn model and the window live in Assistant.qml, outside
the window's loader, so closing the card loses nothing and a reply keeps
streaming while it is closed. Tokens reach the model on a 50 ms tick
rather than per token. Prose goes through Notify.sanitize, because model
output can quote a search result and a remote image in it would be
fetched on render. Code blocks get a copy button once their fence closes.
The history panel lists conversations and searches them through the
daemon's full-text index.
