 ### standard packages

- `std/mem` allocator contract over byte allocation: `Allocator` with `?*mut anyopaque` context, `heap`, `alloc(allocator, size, alignment) ?*mut u8`, and `free(allocator, ptr, size, alignment)`
- `std/mem/heap` legacy compatibility wrappers: `alloc(size usize) ?*mut u8` and `free(ptr ?*mut u8)`
+- `std/mem` allocator contract over byte allocation: `Allocator` with `?*mut anyopaque` context plus `alloc`, `realloc`, and `free`; failed nonzero reallocation preserves the original allocation, while zero size frees it
