Yet another overhaul: remove all visualizations to focus on the simulation

[philiplinden]

Major Changes

• Removed Bevy game engine dependency
• Switched to Krabmaga for simulation framework
• Implemented basic relativity concepts
  • Added clock with proper time and coordinate time

Development Process

• Started using Cursor for code writing
• Focused on implementing relativity basics from educational video series
• Simplified approach by removing complex UI elements
• Prioritized learning Rust fundamentals and making tangible progress

Research and Resources

• Studied video series on relativity
• Reviewed research paper on lunar time scales

Developer Notes

• Recognized the need to focus on core functionality rather than perfecting UI
• Found Krabmaga to be more straightforward and faster to compile compared to Bevy
• Acknowledged the importance of practical implementation over theoretical design

This version represents a significant shift in the project's direction, back to first principles and focusing on core simulation functionality and relativity concepts while simplifying the development process.
