v0.3.0

⚠️ Breaking changes

• Minimum Go version is now 1.24 (previously 1.18). The range-over-function iterators are no longer behind build constraints — the iter package is now a baseline dependency, so older toolchains are no longer supported.
• Len() is no longer nil-safe. Calling Len() on a nil *OrderedMap now panics instead of returning 0. As with the other methods, a map must be created via New() or WithCapacity().

✨ Added

• Collect() — builds an OrderedMap from any iter.Seq2, preserving the order in which pairs are yielded.
