Mark ChristiansenandDanilo Leal d6b58bb948 agent_ui: Use agent font size tokens for thread markdown rendering (#41610)
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.

* Updated the VSCode import logic to recognize and import the new
`agent_buffer_code_font_size` setting.

**Font size application in agent UI:**

* Modified the agent UI rendering logic in `thread_view.rs` to use the
new `agent_buffer_code_font_size` for code blocks, and to fall back to
the agent UI font size if unset.

* Implemented a helper method in `ThemeSettings` to retrieve the code
block font size, with fallback logic to ensure a value is always used.
* Updated the settings application logic to propagate the new code block
font size setting throughout the theme system.

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
