leftibot 5cebd2cd22 Address review: add call stack and filename to wrapped script exceptions
- Catch Boxed_Value in AST_Node_Impl::eval() and wrap in eval_error so
  call stack accumulates as the exception propagates through the AST chain
- Add eval_error constructor accepting filename + Boxed_Value
- Populate filename on wrapped eval_error in chaiscript_engine::eval()
- Extract original boxed value in Try_AST_Node for script try/catch semantics
- Unwrap boxed value in internal_eval/internal_eval_file to preserve
  script-level exception identity across nested eval() calls
- Add tests for call stack presence, filename population, and
  exception_specification backward compatibility

Requested by @lefticus in PR #682 review.
