Invoke the internal entry function through the generated exception handler
and truncate its INTEGER result to the process exit status.

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.

- Parameter syntax lands end-to-end: ARRAY OF T (rank 1, bounds travel
with the argument) and ARRAY[l:u,...] OF T (any rank, literal bounds as
a checked contract). Element type and rank must match exactly.
- Flattened ABI: each rank-R array parameter becomes a data pointer plus
kBoundArgsPerDim i64 bounds per dimension. The callee rebuilds
ArrayMetadata from those bounds (ArrayHandler::bindArrayParameter via a
binder callback injected by CodeGen, so FunctionGen stays ignorant of
the array subsystem); the checked-indexing pipeline is reused unchanged.
- BYVAL (the CIE default) copies the whole buffer at callee entry
(malloc+memcpy, never freed — consistent with the string policy) so
callee writes stay invisible; BYREF binds the caller's buffer.
- Bounded-parameter contract: compile-time comparison when the caller's
bounds are constants, else a runtime [Fatal] check
(RuntimeCheck::emitArrayArgBoundsCheck).
- marshalCallArgs gains the array branch and a call-site line number
(CallStmtAST now carries one); whole-array-to-scalar keeps a clear
error, FUNCTION RETURNS ARRAY is a dedicated parse error.
- Verified: BYREF fill/sort-style mutation, BYVAL copy invisibility,
2-D bounded params, ARRAY OF <record> with field writes through the
parameter, bounds-contract mismatches at compile time and run time.

- Reserve TYPE/ENDTYPE/SET/DEFINE (-600 token block); SET/DEFINE parse to
dedicated not-implemented errors (RANDOM precedent).
- New TypeAST.h: enum/pointer/record decl nodes, designator chain
(DesignatorExprAST + Index/Field/Deref accessors), AddrOfExprAST,
DesignatorAssignStmtAST. Bare-name and single-index shapes degrade to
their legacy nodes, so existing programs produce identical ASTs.
- ParserType.cc: TYPE declarations (top-level only, enforced via a
ParseBlock depth counter), DECLARE-only record bodies with local
field-level error recovery.
- Postfix [ ] . ^ chain in ParseIdentifierExpr; prefix ^ (address-of,
designator operand only) in ParseUnary; assignment targets rebuilt on
the same suffix parser.
- Parameters: ParamDecl{name, type, mode, array rank/bounds} replaces the
(name, type, byref) tuple. Pass mode is sticky across parameters and
BYREF is rejected in FUNCTIONs, both per guide §8.3 (the old per-param
reset made the guide's own SWAP example pass Y by value). ARRAY OF T /
ARRAY[l:u,...] OF T parameter syntax parses; codegen rejects it until
the parameter-passing phase lands.
- CodeGen stubs report clear not-implemented errors for the new nodes so
nothing is silently ignored.

(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.
