Module unsafe_ffi_tracker

Expand description

Enhanced memory tracking for unsafe Rust and FFI operations

This module extends the basic memory tracking to handle:

Unsafe Rust memory operations (std::alloc::alloc, raw pointers)
FFI memory operations (malloc, free from C libraries)
Cross-boundary memory transfers
Safety violation detection
