[Bug] Mouse drag-to-select intercepted by click-to-copy functionality in CLI

Bug Description
Mouse text selection is broken in this Claude Code CLI session: click-and-drag is intercepted as click-to-copy instead of doing normal native terminal text selection. This is a severe usability regression. Drag-to-select is a fundamental terminal interaction, and having it hijacked is genuinely disruptive — I could not select any text in the conversation.

Notably, I am NOT seeing this behavior in my other Claude Code CLI sessions, which suggests it's a recent, experimental, or session-scoped change rather than a long-standing default. There is no documented way to disable it.

Please either revert this, make it opt-in (off by default), or add a config/settings toggle to disable mouse capture / click-to-copy so native terminal text selection works again. As it stands the pattern is actively hostile to normal terminal workflow.
