Introduced symbol files for various Game Boy systems (CGB, AGB, MGB, SGB) to define boot sequences and functionalities. Included CPU instruction behavior tests, with detailed coverage of standard operations and interrupt handling. Added documentation for test execution and internal framework operations.
This commit sets up a foundational CPU simulation with registers, a memory bus, and an initial instruction set implementation in Rust. It includes operations like ADD, SUB, AND, and bit manipulations, as well as basic project configurations through Cargo and IDE settings.
