Bevy harvest loop

When to use

Load this when crops advance on a timer and a harvest message records the yield.

ECS shape

• Components: growth elapsed and a stage index you define.
• Resources: the last visit and the season scale live in resources (bevy-data-resources).
• Systems: step growth on FixedUpdate. Use .chain() so harvest reads the stage growth just wrote.
• Messages: Harvested is the one-shot yield fact. Inventory applies it in bevy-inventory-system.
