Four new tests overlapped: plan-time and spawn-time attested-death overrides
both exercised the same predicate via monkeypatched lambdas. Collapse to:
- one end-to-end test using a real attestation marker in a tmp home: dead
attested gateway keeps the plan under Desktop ownership, survives the
spawn-time re-check, and the marker is consumed by the spawn;
- one probe test: no marker / null or non-list pids / non-dict / non-JSON all
read False (fail closed), alive and clean-exit read False, read-only when
it does read True.
Existing #76129 tests keep their attested_gateway_died=False pins unchanged.
