test_crash_cells carried its own marker parser and identity rule, and it
decides the orphaned_update verdict. It disagreed with the product on three
inputs: a float started_at (product: malformed, copy: live), a create time
1.5 s off (product: live within its 2.0 s tolerance, copy: dead at 1.0 s) and
a run: line before delegate: (product: delegate live, copy: dead, it read
line 4 only). The self-check claimed parity but never called update_lock and
used the test's own pid, which the product judges by exact incarnation.
_marker_live now asks update_lock._parse_marker(...).owner_live() /
delegate_live(); the crash cells run in a pytest process on the same Windows
host as the marker's pids, so the product's process table reads them as the
updater does. The self-check marks a separate live process with an integer
started_at, compares the oracle to judge_marker, and adds the three rows.
The ORPHAN_RELEASE_GRACE poll is unchanged.
