Module utils 

Memory management utilities for plugins

This module provides safe wrappers around the unsafe FFI memory management operations required by the plugin API.

All returned buffers use into_boxed_slice() to guarantee len == capacity, so standard_free_string(ptr, len) can safely reconstruct and drop a Vec.
