evidence(perf): re-record the calibration against the content-addressed digest

The digest fix changes the harness identity a third time, from af32f04ddbad to
69a3a3f8b074 — this time to a value that is the same on both platforms, which is
the point.

Re-recorded at 2feb496 on a clean tree with the toolchain present: 40 cells,
every outcome valid and every cell timed, launcher-e2e exiting 0 having run the
pipeline, dotnet_sdk 8.0.425, 40/40 reproduced with no cell whose outcome
changed, environment not invalidated, gate dormant, no decisive workload timed.
