Fix mouse wheel scrolling

chapterjason · claude · chapterjason · commit 910d609047dd · 2026-04-20T22:25:54.000Z
- tmux.conf: set-option -g mouse on so wheel events route into tmux's
  copy-mode scrollback when the shell fills the screen.
- .xterm .xterm-viewport override: overflow-y: auto so xterm's own
  viewport accepts wheel events again instead of blocking them via an
  inherited/overridden overflow rule.
