fix(compiler): correct CIE semantics and diagnostic locations

2026-10-16T13:21:05Z

Use standard WHILE headers and default-public class fields, resolve pseudocode identifiers without case sensitivity, and check signed i64 literal boundaries before conversion. Preserve source locations across recursive emission and function diagnostics. Add 22 regression cases and update compiler examples and documentation. Validated all 69 CTest entries with the original Linux Actions seed and verified the release package's embedded, native and IR output paths.

feat: implement CIE 9.1 text file handling (OPENFILE/READFILE/WRITEFILE/CLOSEFILE/EOF)

Front end: OPENFILE/READFILE/WRITEFILE/CLOSEFILE plus reserved mode keywords READ/WRITE/APPEND (RANDOM reserved with a dedicated not-implemented error); statement nodes in new FileAST.h, parsing in new ParserFile.cc; EOF joins the Builtins table as the 12th builtin and CallExprAST now carries a line number for its runtime diagnostics. Runtime: new FileHandler (StringHandler-shaped leaf) lazily synthesizes internal __cps_file_* helper functions and a 16-slot open-file table keyed by filename content (strcmp — STRING '=' is pointer identity). EOF is an fgetc/ungetc peek; READFILE grows a malloc/realloc line buffer and strips a trailing CR; fopen uses text modes so mingw-w64 line translation works. File-free programs get byte-identical IR. All misuse (not open, wrong mode, reopen, fopen failure, read past EOF, table full) dies with the existing "[Fatal] line N:" pattern via a new RuntimeCheck::emitErrorAndExit overload taking runtime printf args. Also fixes a pre-existing ArithmeticHandler hole surfaced by adversarial review: mixed-width integer operands (i1 BOOLEAN / i8 CHAR vs i64) now widen via ZExt instead of emitting invalid IR, and remaining type mismatches get a clean diagnostic; -EOF(f) and -IS_NUM(x) compile.
