Compose the conversation thread from the shadcn Message, Bubble, and
Attachment components (Base UI under the hood), keeping COSS semantic colour
tokens — outgoing bubbles use the primary variant, incoming use muted, and
shared files/appointments/password-resets render as Attachment cards. Day
separators, sender grouping, and timestamps are preserved.
