In 1.12.1 the press tick runs the pitch arm after turn (`0x514777`), so a swim pitch key starts inside its press, before the frame's packets. benilla latched the pitch keys in the frame-time pass, after the packet drain. A pitch press in a frame whose packet rooted the mover sent no pitch start at all.
`press_tick` now runs the pitch emitter after the turn arm, and its start or stop goes out after the turn's message. `stop_pitch_keys` and the mouse-look hand-off are unchanged. The latch facts already match: the stop is sent only while swimming (`0x5147e9`), and a stun clears the latch either way (`0x5147fa`).
Test: a swimming pitch press in a rooting frame sends the pitch start, the stop, then the root ack. It fails with the arm in frame time.
