Walkthrough

This PR consists primarily of code formatting and documentation adjustments across the codebase. Changes include repositioning parameter labels and inline comments in function signatures, normalizing code style by adding braces around single-statement conditional blocks, and minor whitespace adjustments. Additionally, the PR introduces two new utility libraries: Bytecode for bytecode manipulation operations, and SSTORE2 for storing data as contract bytecode. Several mock contracts receive new event and error declarations to support additional test scenarios.
