feat: wood consumption for patrol and study

Patrol and study now consume 1 wood from the village woodpile on completion, recording an item_consumed economic event. This gives wood a purpose and creates resource pressure between gathering and work-support activities. Familiarity serialization switched from raw Dictionary to sorted Array of {id, score} pairs for deterministic JSON checksum output across save/load.
