Is your feature request related to a problem? Please describe.

A typical typed SQLAlchemy model looks like this:

class Model(Base):
    name: Mapped[str] = Column(Unicode(100), nullable=True)

This works fine with mypy, but triggers the following error with Pylance/Pyright

Expression of type "Column[Unicode]" cannot be assigned to declared type "Mapped[str]"

Same for relationship

Describe the solution you'd like

Make Column and relationship inherit from Mapped

Additional context

I can make a PR if you're okay with this.

Have a nice day!
