fix(tests): align suite with persona-neutral strict-closure contract

Remove shelved identity/drive tests that existed to justify premature
persona wiring, and update remaining tests to match the current runtime
contract: empty vault triggers unknown_domain gate on first turn, versor_apply
always closes to unit versor, and null-cone preservation is deferred to an
explicit geometry API.

562 passed, 4 skipped, 0 failed.
