feat(all): add ruff as default linter and additional clean up

[spencer-tb]

🗒️ Description

Pre-dominantly adds ruff as our default linter to replace flake8, black & isort. Extra clean-up items are mentioned below.

🧑‍💻 .vscode

The settings.recommended.json has be split into 2 files:

• settings.json: locked config that users of the repo MUST use.
• .settings.local.recommended.json: settings that users can change, for example python testing extension related.

💥 Removal of tf

It seems relevant for us to deperate tf now. Most repo users are familiar with the uv fill etc approach now.

📜 Ruff Related Docstring Changes

A large portion of the diff comes from changes to the python docstrings, via:

One-line docstring should fit on one lineRuff D200
First line of docstring should be in imperative mood: "Handles all fill CLI flag pre-processing."Ruff D401
First line should end with a periodRuff D400

✅ Fixes to noqa: and TODO:

Those that can be fixed now are updated!

With a new linter its seems logical to enforce python docstring standards from now on. Note the warnings appear within VSCode and additionally when running tox.

@spencer-tb could we rebase this to main please? I think it would make it easier to spot issues in the CI if we include the fixes from #905
