fix(compiler): correct CIE semantics and diagnostic locations

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.

 # DESCRIPTION
 
-Declare a class at top level with at least one field. Every field explicitly requires PUBLIC or PRIVATE, without DECLARE. This differs from guide section 10's default-public rule. ENDCLASS closes the declaration.
+Declare a class at top level with at least one field. Fields are public by default; PUBLIC or PRIVATE may be specified explicitly, without DECLARE. ENDCLASS closes the declaration.
 
-Classes use record value semantics: zero initialization, whole-value copying, arrays, pointers, and ordinary function/procedure parameters. Only PUBLIC fields can be accessed externally. PRIVATE fields still initialize and copy with the whole value. Methods, constructors, destructors, NEW, INHERITS, and array fields are unsupported.
