Bug: Truncation Limit Ignored for Local Variables
The serialize() call for local variables doesn't pass through the max_value_length parameter from serialize_frame(), causing local variables to never be truncated even when users explicitly set max_value_length. This breaks the intended truncation behavior for stack frame local variables.
