/**
 * Represents one interpreter call-frame.
 *
 * Frames are pushed for built-ins, user-defined functions, anonymous function
 * handles, and temporary `eval` execution. They provide:
 *
 * - the active workspace for lookup and assignment,
 * - the callable currently being executed,
 * - metadata used by `nargin`, `nargout`, `inputname`, and stack traces,
 * - a linked `parentFrame` chain for MATLAB/Octave-like caller lookup.
 *
 * `InterpreterError` remains in `Interpreter.ts`; this class is intentionally a
 * small data holder so stack-management helpers can use it without depending on
 * the full interpreter implementation.
