Exclude pause/resume from undo; fix verify round-wrap false positive

togglePause no longer writes log entry (shared/turn.js). Lifecycle op, not
player action. Undo stack now targets last real action, not flag flip.
Removed dead pause/resume cases from expandUndo.

verify.js false positive: round wrap via non-nextTurn event (removeParticipant)
not detected — cycleActed never reset, actors flagged as acted_twice. Fix:
detect round change on ANY event, drain removed/inactive before finalize
(avoids false skipped when actor removed mid-round).

Tests updated: togglePause logging test asserts no log; undo test asserts
excluded. Repro confirmed via minimal verify case (removeParticipant r1->r2).
