Refactors collection initializations and comprehensions to use more concise and idiomatic Python syntax, such as set literals (`{...}`) instead of `set([...])`, empty dictionary literals (`{}`) instead of `dict()`, and `dict.fromkeys` for `str.maketrans`.
Also removes unnecessary list creation within `any()` calls.
Migrate to `A | B` syntax for unions (PEP 604) and introduce `typing.TypeAlias` for complex types, leveraging features available in Python 3.10+. This also updates `socket.timeout` to `TimeoutError` and adds `UP045` to Ruff ignores.
Enable Pyupgrade (`UP`) checks in Ruff, which drives the modernization of type hints.
This includes replacing `typing.Deque` with `collections.deque` and `typing.Tuple` with built-in `tuple` where applicable, improving consistency and adhering to modern Python conventions.
This change enables `F401` (unused import) checks in Ruff and configures per-file ignores for intentional top-level imports. The newly enforced check led to the removal of several unused imports across the codebase.
Additionally, the module existence check for `certifi` was modernized to use `importlib.util.find_spec` for a more efficient and robust approach.
* Remove UI delays

Integrates the Ruff linter into the CI workflow alongside Black. This enhances code quality and consistency by catching common issues. Addresses an initial `F821` (undefined name) finding in `__init__.py` identified by Ruff, ensuring explicit module referencing.
