fix(terminal): restore Claude scroll-back on macOS trackpads (#154)

Deterministic claude --version probe seeds cliVersion so wheel-forwarding
to Claude's transcript engages (banner scrape was unreliable on 2.1.187+
and resumed sessions). Shift+wheel reads the dominant axis so a trackpad's
horizontal Shift-scroll reaches local scrollback. New per-device
"Wheel Scrolls Local History" opt-out. Wheel reports use a fire-and-forget
send path so they no longer flicker the pending-bytes indicator.
