chore(pi-natives): removed mimalloc allocator integration from pi-natives

- Removed mimalloc from workspace and crate Cargo.toml dependency lists.
- Eliminated the global `MiMalloc` allocator registration from `pi-natives`.
- Updated Cargo.lock by deleting stale `mimalloc` and `libmimalloc-sys` package entries.
