+#### chore: Implement PEP 563 deferred annotation resolution (#459)
+
+- Add `from __future__ import annotations` to defer annotation resolution and reduce unnecessary runtime computations during type checking.
+- Enable Ruff checks for PEP-compliant annotations:
+  - [non-pep585-annotation (UP006)](https://docs.astral.sh/ruff/rules/non-pep585-annotation/)
+  - [non-pep604-annotation (UP007)](https://docs.astral.sh/ruff/rules/non-pep604-annotation/)
+
+For more details on PEP 563, see: https://peps.python.org/pep-0563/
