Implement gradual evolution mechanics and simulation time handling in Owniverse.GI

- Added `blastability` property to entities for vulnerability tracking. - Enhanced planet string parsing with validation and error handling. - Introduced `simulation_rules.md` to document evolution mechanics and rules. - Created tests for time progression and stellar evolution rules, ensuring correct handling of fractional years and resource production. - Implemented `simulation_time.gd` for managing accumulated time and year processing. - Updated tests to validate legacy save compatibility and migration to new time schema.
