Refactor build system and implement complete renderer system

- Split monolithic build.rs into modular async generators
- Add renderer override system with type-safe dispatch
- Implement command template macro for consistent command definitions
- Add proc-macro crates for command and renderer systems
- Reorganize directory structure for better separation of concerns
- Update documentation to reflect new architecture
