Each forwarded raw-input event is written to g_raw_slots[head++ % kRawSlots] and
a WM_INPUT carrying that slot's ADDRESS is posted to the game, which reads it back
through hk_GetRawInputData. With only 64 slots, a burst that queues more than 64
WM_INPUTs before the game pumps could overwrite a slot before the game reads it,
so it would decode a newer event for a stale message. No memory unsafety (the
address stays in-bounds), but wrong event data under backlog.
Grow the ring to 512 (a few tens of KB) so realistic input rates can't lap it.
Deliberately not per-slot consume-tracking: that would permanently exhaust slots
and silently stop forwarding for a game that ignores WM_INPUT, whereas a large
ring always forwards and only risks a rare stale read under extreme backlog.
Also drops the "publish() synthetic-input timing" review item: verified it uses
GetTickCount64() (thread-safe), not ImGui state -- not a bug, no change needed.
