Transaction Science 836d0255df wai packaging stack: #426, #438 and #452's GPU tier, squashed onto main
One squashed history of three stacked PRs, onto main at b16816671:

- #426 (wai/pack-efficiency): a title's whole AV1 ladder in one package over one
  integer base; several floor rungs (packaging §7.1), a re-pack from a parent
  (§11.5), a floor that is the ladder's own CMAF (§7.7), a floor-only profile
  (§7.8), a streaming pack (§11.4), and the independent verifier at scale (§9.4).
- #438 (wai/cross-fabric): each pack and verify step on the fabric with the least
  measured energy (§11.6); the `fabrics` member of measurement claims
  (jwp-receipts §2.4.8, energy-measurement §6.3); the wai-pack-gpu crate;
  `wai-pack fabric`; `wai-pack floor-decode`.
- #452 (wai/gpu-int-tier), its GPU-tier part only: claiming decode-equivalence on a
  GPU (determinism-tiers §5), the WGSL integer semantics suite, the rules check on
  naga's IR, and the kernels' shift masks and min(max()) clamps.

Left out, by the review's split (EN-C takes it over): #452's platform decode in
dispatch, its commits 6ad92e2e8, 8695bc75f and fed8694f4 and its CHANGELOG entry:
extensions/platform-decode.md, platform-decode-conformance/, wai::platform_decode,
wai-web's platform_decode bundle and demo, and its two SPEC.md sentences.

#438's research note is not carried as written: it is rewritten as
wai/research/cross-fabric.md, with hardware named by architecture, PCI id and OS
version, and every table marked as one run. floor_decode.rs and a wai_pack.rs
comment name the platform's media engine and a full-length film the same way.

wai/CHANGELOG.md is the union of both sides' entries, the stack's first.
