🔖 release v1.4.3

## 1.4.3

* [CHORE] optimize `encode` traversal internals and hot paths with lower allocation overhead
* [CHORE] add internal `KeyPathNode` path caching for lazy materialization and dot-encoded path reuse
* [FIX] avoid `RecursionError` in deep key-path dot encoding by making `KeyPathNode.as_dot_encoded` iterative
* [FIX] ensure strict null handling applies RFC formatter behavior for bare-key output (e.g. RFC1738 space handling)
* [FIX] avoid mutating caller-owned root list/tuple elements when `EncodeOptions.filter` is callable
* [CHORE] remove unused `KeyPathNode.total_length` state to keep nodes lightweight
* [CHORE] expand encode regression and internal helper tests (path caching, list format generators, strict-null formatting, mutation safety)
