Feature request: Allow users to disable the 'ctrl+c to copy' hint in status bar

Summary

When text is selected in the Claude Code terminal UI, a ctrl+c to copy hint appears in the bottom status bar. There is currently no way to disable or hide this hint.

Requested Change

Add a configuration option in settings.json to allow users to suppress this hint. For example:

{
  showCopyHint: false
}

Motivation

• The hint is hardcoded UI behavior with no toggle
• Experienced users already know how to copy selected text and find the hint visually distracting
• Consistent with Claude Code's philosophy of giving users control over UI elements (e.g., autoScrollEnabled, statusLine customization, autoCompactEnabled)

Environment

• Platform: Windows 11
• Claude Code terminal UI
