Add standard library modules: - Std::String: strlen, strcmp, concat, copy, starts_with wrappers - Std::Map: linear-probing hash map with String keys, int values Add error handling: - Result and Option algebraic enum examples - ? try operator for automatic error propagation in HIR lowering Compiler bugfixes: - Fix sizeof() for user-defined structs (new hSizeOf HIR node) - Fix HIR type lowering for char8, bool8, int8, uint8, etc. - Fix let statement lowering for pointer types (*char8 → int* bug) - Fix PrintInt ABI mismatch (int64_t → int in io.c) - Fix Makefile test bug (_test_tmp_pkg already exists) Documentation: - Rewrite README.md with features, examples, project structure - Add docs/LanguageRef.md — complete language reference - Add docs/Stdlib.md — standard library documentation - Add docs/BuildAndTest.md — build and test guide New examples: strings, map, result_option, try_operator (13 total)
