feat(rendering): compare the incremental shadow scene

Construct Slice F's non-drawing scene only for lifecycle automation, drain accepted static and live deltas at the final update boundary, and compare exact current-path fingerprints at cadence and checkpoints. Publish bounded mismatch, journal, index, digest, and memory evidence without changing normal launches or draw submission.

Release: 8,211 passed, 5 skipped.
