Note

Low Risk
Changes are version metadata, changelog documentation, and docstring deprecation labels—no runtime logic changes in this diff.

Overview
Release packaging for chainladder 0.10.0 (scheduled July 29, 2026): bumps the published version from 0.9.2 to 0.10.0 in pyproject.toml and uv.lock, and adds a full Version 0.10 section to docs/library/releases.md summarizing enhancements, fixes, deprecations, maintenance, and dependency changes since v0.9.2.

Docstrings for cl.options.get_option, set_option, and reset_option now mark the legacy option parameter as deprecated in 0.10.0 (previously 0.9.3), aligning Sphinx deprecation notices with the release.
