Commit Message

fix: Improve typing of @component and allow TypedDict output types (#9396)

- Add type annotations to the `_Component.__call__` function that
  backs `@component`. This fixes "decorator ignored" warnings of
  Pyright in "strict" type-checking mode.

- Type-check that a `@component` class conforms to the `Component`
  protocol (i.e., that it has a `run()` method).

- Relax the `run()` return type required by the `Component` protocol
  from `Dict[str, Any]` to `Mapping[str, Any]`. The former is
  incompatible with `TypedDict`, which makes it impossible to
  type a component's precise outputs. `Mapping` fixes this because
  it is covariant, i.e. the value type may be more specific than
  `Any`.
