An on-glass 'touch does nothing' currently leaves NO trace: log the first
SS_TOUCH per session at info (proves the client sends + we decode), and warn
when a packet carrying a pointer magic fails the body parse (layout mismatch)
instead of vanishing into the unknown-magic drop.

The Moonlight leg of design/pen-tablet-input.md §4: DESCRIBE now advertises
SS_FF_PEN_TOUCH_EVENTS wherever pen injection exists (Linux+uinput, same gate
as HOST_CAP_PEN — elsewhere the flag stays 0 and Moonlight keeps client-side
mouse emulation exactly as today). SS_PEN packets merge over last-known state
into state-full PenSamples (BUTTON_ONLY per spec carries no position; unknown
contact pressure 0.0 inks at full scale; UP keeps proximity only for clients
that demonstrated hover) and drive the same PenTracker→VirtualPen chain as the
native plane — Moonlight iOS + Apple Pencil now exercises the full injection
path end to end. SS_TOUCH forwards as wire touch on a synthetic 65535² surface
with CANCEL_ALL replayed per tracked contact. No stroke timeout on this plane:
ENet is ordered/reliable and Moonlight doesn't heartbeat a stationary pen.
Packet layouts pinned against moonlight-common-c Input.h/Limelight.h upstream.
