Read-only mode copies line numbers with code, making copy-paste unusable

[SunMendi]

What happened?

When using Qwen CLI in read-only mode, code blocks are rendered with line numbers.
When copying the code, the line numbers and separator characters (│) are also copied.

This makes pasted code invalid and requires manual cleanup line-by-line.

• Steps to Reproduce

1. Run Qwen CLI in read-only mode
2. Ask for code generation
3. Copy the generated code
4. Paste into an editor

-Actual Behavior
Copied text includes line numbers and separators:
│ 69 ...
│ 70 ...

• Impact
  This significantly hurts developer productivity and copy-paste workflows.

-Suggested Solutions

• Add an option to disable line numbers
• Strip line numbers on copy
• Provide a "copy clean code" mode or flag

What did you expect to happen?

Copied code should be clean, without line numbers or UI decorations.
