Walkthrough

This pull request introduces changes across multiple areas: header management in interpreter.h (adjusting includes and forward declarations), enhancements to fuzz testing infrastructure by introducing a good_data flag mechanism to gracefully handle invalid input data across multiple fuzz test files, documentation updates to the LIMITED_WHILE macro, refactoring of serialization handling in script_flags.cpp, and modifications to wallet rescanning logic in CWallet::AttachChain to unconditionally infer wallet birth time and adjust rescanning windows based on chain state.
