Enable xterm SGR mouse reporting in the dashboard TUI and dispatch
wheel events to the focused pane: task detail logs, Git lists
(commits/branches/worktrees), and Files view (tree or preview).
Mouse mode is enabled after Ink mounts so the leading ESC of wheel
reports never arrives alone — avoiding spurious Esc keypresses. We
omit motion-tracking modes so terminals still own drag gestures and
Shift+drag native text selection keeps working.
