[Feature Request] Add scroll-only mouse mode to disable clicks while preserving wheel scrolling

Bug Description
Feature request: scroll-only mouse mode in full-screen view In full-screen mode, mouse handling is all-or-nothing. With the mouse enabled, clicking into the terminal to focus it (or any stray click) can accidentally hit buttons or expand/collapse tool output. The only mitigation, CLAUDE_CODE_DISABLE_MOUSE=1, also kills mouse-wheel scrolling, which is the part I want to keep. Please add a mode that ignores mouse clicks but keeps wheel scrolling — e.g. a CLAUDE_CODE_DISABLE_MOUSE=clicks value or a mouseMode: "scroll-only" setting. That would let me scroll with the wheel (I have CLAUDE_CODE_SCROLL_SPEED set to 5) without accidental clicks landing on interactive elements.
