- example.py: mark the base Example.scope field frozen so the (#7798)

Literal[api]/Literal[python] subclass overrides are covariant
  read-only narrowings. Subclass fields stay writable at runtime.
- method_definition.py, options_chains.py: pydantic 2.14 types
  FieldInfo.annotation as TypeForm[Any] | None, which ty rejects in
  Union[]/Annotated[] and where  is expected; bind it as Any.
  Use FieldInfo.get_default(call_default_factory=True) instead of
  calling the default_factory union directly.
- economy_views.py: read data/obbject_item without None defaults in the
  IMF shipping views. charting always sets obbject_item, and data is
  only popped when present and not None.- finra, jodi, eia: annotate @asynccontextmanager/@contextmanager
  functions with AsyncGenerator/Generator instead of the deprecated
  AsyncIterator/Iterator return types.
- charting: cast the darts forecast dataset to TimeSeries before
  indexing so .all_values resolves instead of hitting ndarray.
- fred, imf, nasdaq, sec, tmx: turn off invalid-attribute-override and
  invalid-mutable-override for models/** only, following the cboe
  precedent. Provider models extend the standard models by narrowing
  query params to Literals or widening fields to Optional, which these
  rules flag by design.
