Added documentation for: - Std::Fs (DirExists, Mkdir, ListDir) - Std::Mem (Alloc, Free, MemEq, New) - Std::Set<T> (Set_New, Set_Add, Set_Has) - String_Find, String_Replace, String_Format Updated PLAN.md blockers (all resolved) and self-host status. Updated README.md project structure and feature table. Updated BuildAndTest.md with new stdlib modules and path syntax. Also includes: - CLI path argument fix (build/check/run accept project path) - Remove dummyFunc from parser - Fix String_Replace to use String_Concat instead of buggy str_join2
