On Windows, Zig's built-in libc and MSVC's CRT maintain separate heaps, so calling free() on memory allocated by the library causes undefined behavior. Add ghostty_free() that frees through the same allocator that performed the allocation, making it safe on all platforms. Update format_alloc docs and all examples to use ghostty_free() instead of free(). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
