* fix(pack): notarize macOS builds only once
* perf(pack): separate type validation and defer bounded Windows caches
* test(e2e): bound BuildKit cleanup job away from pack cache save
The deferred Windows pack-cache job checkouts the repo, so slicing
clean-closed-pr-buildkit to EOF made the no-checkout assertion fail.

* test(ci): bound cache cleanup assertions to their job
* fix(ci): preserve cache provenance when the release branch advances
* perf(ci): reduce compression work in Windows cache handoff
* fix(ci): align Windows cache restore and persistence paths
* perf(ci): retain latest complete Windows artifacts for repeat builds
* fix(ci): keep newer pack caches when ancestor saves finish later
Prefix pruning in cache-maintenance used cache creation time, so an older ancestor finishing after a newer same-ref release deleted that newer cache. Prune only when the validated source SHA is the current commit.
