=====
* Upgrade to Rust edition 2024.
* Add `size_hint`, `ExactSizeIterator`, and `FusedIterator` to `Iter`, `IterMut`, and `IntoIter`.
* Fix 2× iteration slowdown vs `slab`: `ObjId::from_index` now uses `new_unchecked` in release builds, allowing the compiler to eliminate key construction when the result is discarded.
* Add GitHub Actions CI (test on stable/beta/nightly, clippy, rustfmt).
* Add criterion benchmarks comparing `obj-pool` vs `slab`.
* Rewrite README with usage examples and benchmark data.
