feat(assistant): entry line, file state, staged files and a picker

The card has three states: an entry line, a file state for staged files with Chat about it, and the chat. SUPER+Home resumes a conversation active in the last 10 minutes and otherwise starts a new one. The paperclip opens a picker drawn in the card, since a system dialog would open beneath the overlay that holds the keyboard. Button gains a font alias for the paperclip glyph, and the canvas a socketPath property so a check can point it at a scratch daemon.
