• I passed tests locally for both code (uv run pytest) and documentation changes (uv run jb build docs --builder=custom --custom-builder=doctest)

---

Note

Low Risk
Small refactor plus I/O test coverage; Development keeps its own three-argument _param_property, so incremental behavior should follow the moved helper unchanged.

Overview
Triangle pickle I/O is documented at the module level in chainladder/core/io.py, with imports reordered and an unused joblib import dropped from that file (pickling still uses dill).

Development estimators:_param_property is added as a static helper on DevelopmentBase, and the duplicate implementation is removed from IncrementalAdditive, which now calls the shared helper for zeta_. Type hints in DevelopmentBase switch from TriangleLike to Triangle for _set_fit_groups.

Tests:test_triangle_to_pickle exercises Triangle.to_pickle / read_pickle round-trips for single- and multi-dimensional sample triangles (raa, clrd).
