Every entity's zone-removal subscription dropped its IFF override for whatever
left the zone, and TryDock removes the docking ship, so a scenario stance was
lost one way (the other entity forgot; the docked ship, deactivated, kept its
own) as soon as the player docked. The removal event already tells the two
apart: TryDock parents the ship to its dock before removing it, and every
leaving-for-good path (death, warp, unload) leaves with no parent. The override
is now dropped only for an entity that leaves unparented.
Tests: a hostile stance holds both ways, including the live hostility each side
tracks, across dock and undock; a destroyed entity takes the player's stance
toward it with it. UndockingAdmitsWithNoAgent commits Soul's probe: undock
admits unpiloted, active, with no agent.
