Release Notes: - N/A --- Previously, agent markdown rendering used hardcoded font sizes (TextSize::Default and TextSize::Small) which ignored the agent_ui_font_size and agent_buffer_font_size settings. This updates the markdown style to respect these settings. This pull request adds support for customizing the font size of code blocks in agent responses, making it possible to set a distinct font size for code within the agent panel. The changes ensure that if the new setting is not specified, the font size will fall back to the agent UI font size, maintaining consistent appearance. (I am a frontend developer without any Rust knowledge so this is co-authored with Claude Code) **Theme settings extension:** * Added a new `agent_buffer_code_font_size` setting to `ThemeSettingsContent`, `ThemeSettings`, and the default settings JSON, allowing users to specify the font size for code blocks in agent responses.
