Show the full prompt text in the composer input #5370

Summary

The composer input does not show the full prompt text. Longer text is visually truncated inside the input instead of being fully readable or wrapping/scrolling clearly.

Current behavior

In the composer at the bottom of the project/design-system flow, the prompt text is clipped. The screenshot shows the input containing a Chinese prompt, but the visible line ends with an ellipsis-like truncation and the full text is not shown in the available input area.

This makes it hard for users to review or edit the prompt before sending.

Expected behavior

The composer should make the full prompt text accessible. Depending on the intended layout, it should either:

• Wrap long prompt text onto additional lines,
• Provide clear horizontal/vertical scrolling without clipping important text, or
• Expand the input area enough to show the current prompt content.

The text should not appear cut off in a way that hides what will be submitted.

Steps to reproduce

1. Open a project or design-system extraction flow.
2. Put a longer Chinese prompt into the composer input.
3. Observe the visible text inside the input before sending.
4. Notice that the prompt is not fully displayed.

Notes

A screenshot was provided showing the composer input with the prompt text clipped inside the highlighted area.

Why this matters

Users need to verify and edit prompts before sending. If the input hides part of the prompt, users may submit incomplete or unintended instructions.
