Material3AguiTextRenderer

Draws prose with Material 3's Text.

The difference from PlainAguiTextRenderer is entirely that this one can be styled from above. BasicText has no ambient text style, so the default renderer draws at TextStyle.Default -- 14sp, black, whatever the theme says -- and a host that set a type scale or a content colour would watch the transcript ignore both. This reads LocalTextStyle and the ambient content colour, which is what makes the slots in Material3AguiComponents able to dim reasoning, or a host able to enlarge the whole transcript, without replacing the renderer.

Still not a Markdown renderer. The streaming flag is accepted and ignored, and **bold** draws as five literal characters and a word. That is the same position agui-compose takes and for the same reason -- TEXT_MESSAGE_CONTENT carries a string and says nothing about its syntax, so which flavour to parse is the application's decision -- and this module does not overturn it merely by being one layer higher. What it does is leave the seam intact: an application that wants Markdown provides its own AguiTextRenderer and keeps every slot in this module, because the prose slots here draw through LocalAguiTextRenderer rather than calling Text themselves.
