Summary

This removes a hack in the protocol satisfiability check that was previously needed to work around missing assignability-modeling of inferable type variables. Assignability of type variables is not implemented fully, but some recent changes allow us to remove that hack with limited impact on the ecosystem (and the test suite). The change in the typing conformance test is favorable.

Test Plan

• Adapted Markdown tests
• Made sure that this change works in combination with astral-sh/ruff#20517
