* feat: added guestBranchKind enum to categorize branch types feat: added missingFunctionPolicy enum to define behaviors for missing function scenarios refactor: added handle guest branches and report missing functions feat lookupFunction to utilize new dispatch logic and improve error handling for unregistered functions * fix: fix test conflict * feat: added debug sound driver logs * feat: emmiter for return * feat: added recompiler reporter feat: added strict diagnostics flag for heavy debug calls * feat: staticc table insted of hashmap for runtime * feat: back file to ignore * feat: explode code across helpers and classes * feat: update codegen test feat: better guest nop check * feat: fix link problem on linux * feat: fix Segmentation fault
