fix: resolve all basedpyright warnings

- Use collections.abc.Generator/Iterable instead of deprecated typing imports
- Replace Optional with union syntax (X | None)
- Add explicit type annotations to eliminate reportUnknownVariableType
- Use typing.cast for untyped mistletoe attributes (content, level, line_number)
- Replace mutable default arguments with None defaults (reportCallInDefaultInitializer)
- Add ClassVar annotation for model_config (reportIncompatibleVariableOverride)
- Add @override decorator for settings_customise_sources (reportImplicitOverride)
- Annotate class attributes in Tag (reportUnannotatedClassAttribute)
- Add parameter type annotations in test (reportMissingParameterType)
- Assign unused call result to _ (reportUnusedCallResult)
