Module string_c 

C FFI memory management helpers for string and byte buffer allocation.

Provides extern "C" functions for allocating and freeing Rust-owned memory from C code:

• diffsol_alloc_string / diffsol_free_string — allocate/free Rust-owned C strings.
• diffsol_alloc / diffsol_free — allocate/free byte buffers.

These are used by the other _c modules when returning dynamically sized data (e.g. serialized equation blobs) to C callers.
