- Introduced `life_evolution.gd` to manage life evolution processes.
- Implemented `manual_production.gd` for handling production mechanics, including resource management and production steps.
- Created `object_batches.gd` to manage batches of objects, including scaling and appending batches.
- Developed `object_ledger.gd` for tracking physical amounts, available resources, and binding ownerships.
- Added `simulation_module.gd` as a base class for simulation modules, providing a weak reference to the world.
- Established `stellar_rules.gd` for managing stellar evolution and destruction mechanics.
- Introduced `universe_environment.gd` to calculate environmental parameters based on the current state of the universe.
- Updated export path and version code in export_presets.cfg
- Changed project version in project.godot to 0.7.0
- Expanded simulation rules in simulation_rules.md to clarify resource management
- Improved testing framework in tests/README.md to include new civilization budget checks
- Added new tests for batch boundaries and civilization state transitions
- Enhanced civilization_state.gd with shared budget and transition logic
- Refactored owniverse.gd to enforce capacity during life batch initialization
