FlyBrain 0.2.0

New

• Natural spawning. Flies appear on their own during the day outdoors in plains, sunflower plains, meadows, flower forests, cherry groves, forests, birch forests, swamps and mangrove swamps. This is game design, not an ecological model.
• Spawn limit for performance. No natural spawns while a dimension already holds 6 flies (config naturalSpawnMax), because every fly runs its own brain simulation.
• Wild flies despawn. Naturally spawned flies disappear like bats when no player is near. Flies from the spawn egg or /flybrain spawn stay.
• New config section [spawning] in flybrain-common.toml: naturalSpawning (on/off) and naturalSpawnMax.
• The biome list is the biome tag #flybrain:fly_spawns, so datapacks can change where flies spawn.

Fixes and tests

• New automated in-game test for spawning: biome entry, day and night rule, despawn flag and saving.
• In-game tests now report the cause of death when a test fly dies.
