feat: NPC mourning behavior on housemate death

When an NPC dies from starvation, their highest-familiarity companion enters mourning for 100 ticks (~half a day). Mourning NPCs skip work: they rest if energy is low, otherwise wander near home. Mourning_ticks counts down each tick through ActionExecutionSystem and is serialized for save/load continuity with backward-compatible default of 0. This gives the familiarity graph its first behavioral consequence.
