Sync the codebase dependencies

Without explicit --all-extras syncing, some recipes will not evaluate on optional dependencies and functionalities.
The sync recipe will also update the dependencies if possible.

just sync

Before committing

We (I) work with ruff, ty and pytest.

just format check ty test

[!TIP] Install pre-commit hooks: just pc-install.
To keep hooks somewhat fast enough, they will only check (not forcibly fix) for typing and formatting.
