File-Level Changes

Change	Details	Files
Declare the library as PEP 561 typed and align packaging metadata with the change.	Increment the project version from 0.0.8 to 0.0.9 for a new release. Add py.typed to the google_docstring_parser package data so type checkers recognize the package as typed. Raise the requires-python constraint from >=3.9 to >=3.10 to match typing expectations. Update Trove classifiers to drop 3.9, keep 3.10–3.13, and add 3.14, aligning supported versions with the new baseline. Remove the typing-extensions dependency that was only needed for Python <3.10.	pyproject.toml
Align linting and type-checking tooling configuration with Python 3.10.	Update Ruff target-version from py39 to py310 and adjust the comment to assume Python 3.10. Update mypy configuration to python_version = "3.10" so type checking matches the new baseline.	pyproject.toml
Refresh pre-commit hook versions for tooling.	Bump pre-commit-hooks from v5.0.0 to v6.0.0. Bump pyproject-fmt from v2.6.0 to v2.11.1. Bump ruff-pre-commit (Ruff) from v0.11.10 to v0.14.11. Bump mypy pre-commit mirror from v1.15.0 to v1.19.1.	.pre-commit-config.yaml
Replace editor-specific automation rules with general AI usage guidelines.	Add CLAUDE.md documenting communication rules, development philosophy, Python/testing conventions, and tooling usage for Claude AI. Remove the .cursor/rules/custom-rule.mdc file, centralizing such guidance in CLAUDE.md.	CLAUDE.md .cursor/rules/custom-rule.mdc
