Code Review

I've analyzed this PR and found no bugs or performance issues. The fix correctly addresses a zone counting bug where moves that caused a zone to exit joseki due to adjacency were not being counted in the zone's statistics.

What the fix does:

The PR moves the move counting (moves_in_zone and zone_loss increments) to occur before the adjacency check, ensuring that when a zone exits joseki due to being adjacent to a non-joseki zone, the triggering move is still counted.

Why this is correct:

• Moves should be counted while the zone is active, including the final move that causes it to exit joseki
• The early exit via continue is appropriate after marking the zone as inactive
• Subsequent moves in the now-inactive zone correctly skip counting due to the !zoneState.still_joseki[zone] check

The logic is sound and handles all edge cases correctly (multiple zones per move, early exits, threshold checks).
