📄 Description

Summary

Fixes #5975

In widescreen mode, conversation bubbles resize inconsistently when messages contain YAML (or other long-line) code blocks. This happens because the code block's outer <div> wrapper has no width or overflow constraints, allowing the intrinsic width of long code lines to propagate up and influence the parent bubble's layout during scroll reflows.

Changes

Added max-w-full overflow-hidden to the outermost <div> of CodeBlock.svelte
max-w-full ensures the code block never exceeds its parent container's width
overflow-hidden prevents code content from expanding the bubble; the inner <pre> element already provides horizontal scrolling via overflow-x-auto

Test Plan

Open a chat in widescreen mode
Send or view a message containing a YAML code block with long lines (e.g. from this file)
Scroll up and down the page
Verify that conversation bubble widths remain consistent and do not change while scrolling
