Sangokushi II: end the province's commands

The verified province-command end for Sangokushi II, observed as the province
10 to 18 transition. One call presses 0, Return, y in sequence, advances
until the screen settles (masc_msx_step_until_change), and returns the
settled observation with its frame and artifact.

Use it only when the visible prompt is the province command prompt of the
province you are finishing; a macro pressed on another screen is just keys.
The game knowledge this macro comes from — menus, save flow, media pitfalls —
lives in the sangokushi-2 Skill. The machine is shared: an unexpected
result may mean another driver intervened between the presses and the settle;
re-observe before retrying (the msx-play Skill, shared machine).
