Expand description

Message types, content blocks, and streaming events.

These types are the shared “wire format” used across the project:

Providers stream StreamEvent values that incrementally build an assistant reply.
Sessions persist Message values as JSON (see crate::session).
Tools return ContentBlock output that can be rendered in the TUI and replayed to providers.
