Get semantic tokens for the entire file

Return `true` if the [`Module`] was "seen" anywhere in the semantic model. This is used as a fast path to avoid unnecessary work when resolving symbol

Returns `true` if the file should be analyzed as a type stub.

If this type is a `Type::TypeAlias`, recursively resolves it to its underlying value type. Otherwise, returns `self` unchanged.

Create a [`Generator`] to generate source code based on the current AST state.

Returns `true` if the given range intersects with any comment range.

Return true if this type is assignable to type `target`. See `TypeRelation::Assignability` for more details.
