While a reply streams in, pieces of text, tool input or thinking that aren't plain text are now dropped instead of used

What

Claude's replies arrive in small pieces as they are written. Pieces carrying text, tool input or Claude's thinking are now dropped if their content is not plain text. Before, each piece was used as it arrived.

Why

This makes Claude Code sturdier when a reply arrives in an unexpected form.
