test: reduce brittle assertions and test-only runtime paths (#9289)

* test: focus assertions on behavioral evidence

Prune redundant and wording-coupled checks while retaining diagnostic, parser, recovery, and cleanup coverage.

* refactor: remove test-only wrappers and duplicate checks

Exercise production operations through test fixtures, remove unused adapters, and keep managed-member uncertainty guidance under its existing owner.

* test: focus process validation on diagnostic facts

* refactor: remove test-only runtime helpers

Move semantic evidence fixture setup out of runtime and remove unused Windows settle recovery helpers while checking configured defaults independently.

* test: focus artifact diagnostics on format facts

* test: verify retained cleanup guidance delivery
