Isolate CI Testing Strategies for pre-commit, docs and testing

[harryswift01]

Summary

This PR improves CI reliability and clarity by fully isolating the test, documentation, and pre-commit environments. Each CI job now installs only the dependencies required for its specific purpose, removing unnecessary coupling and preventing unrelated dependency failures from surfacing in the wrong job.

Changes

Isolate CI jobs and dependency scopes:

• Updated the CI workflow so that test, documentation, and pre-commit jobs install only their respective dependency extras.
• Removed implicit dependency coupling between CI jobs.
• Ensured failures are confined to the job responsible for the failing component.

Align packaging extras with CI and pre-commit usage:

• Refined optional dependency groups in pyproject.toml to clearly separate testing, docs, and pre-commit concerns.
• Added explicit linting and formatting tools to the pre-commit extra to match the configured pre-commit hooks.
• Made development tooling dependencies explicit and easier to reason about.

Impact

• CI failures are easier to diagnose and attribute to the correct source.
• Documentation or testing dependency changes no longer affect pre-commit checks.
• Contributors can install only the tooling they need for a given task.
• Improves long-term maintainability through clearer separation of concerns.

Great spot Harry! Can you add the other two maintained packages to your list and check it is not the same there.
