One-finger touch was absolute "direct pointing" — the host cursor jumped to the
finger and was recomputed from each touch-start, so you couldn't precisely reach a
target. Now a relative trackpad: the cursor stays put on touch-down and moves by the
finger delta (host MouseMove via nativeSendPointerMove, already supported — no
protocol change), with mild pointer acceleration and sub-pixel remainder
accumulation so slow precise moves aren't lost to Int truncation. Swipe, lift, and
re-swipe to walk it across; tap = left-click at the cursor's current position.
Two-finger scroll / right-click, three-finger HUD toggle, and tap-then-hold-drag are
preserved unchanged; finger-id re-anchoring keeps multi-touch transitions jump-free.
Added Settings → Pointer → "Trackpad mode" (default on); turning it off restores the
old direct-pointing path verbatim.
