Agent Panel: Separate setting for message editor font size

[agu-z]

We added agent_font_size, but users would like to configure the message editor font size separately.

See https://github.com/zed-industries/zed/issues/30200#issuecomment-2889659664

the response font size is also relative to agent_font_size, its smaller. I currently increase agent_font_size to the point where I find the agent responses readable. perhaps this request can be included in the same chunk of work?

perhaps also consider whether a more agreeable default is to have the same consistent font and font size for all three of input area, user input in the response area and the agent output in the response area.

The smaller font size of the code blocks has become a readability issue. It would be better if all areas of the agent panel used the same font size, controlled by agent_font_size.

My question is, why? Why was the agent panel message editor font size decoupled from the buffer font size?

_{^{(and why is it so small??)}}

@timriley explains why this is an issue.

Hey all — closing this issue as this is now available through the agent_ui_font_size and agent_buffer_font_size settings fields. Thank you!
