Upstream trimmed kernel configs (~480 options dropped per config) for faster Firecracker boot; kernel versions unchanged (5.10.259 / 6.1.176). Manifest vendored verbatim from the release; asset sha256s verified against the release sidecar files.

install_state/2 counted an asset as installed if the file existed, so a manifest bump never invalidated the redist cache: nodes kept booting the previous release's kernels from the same asset paths forever. A cached file now counts as installed only when its SHA-256 matches the manifest; stale files are re-fetched (all stale -> reinstall in place, partially stale -> wipe and reinstall). Found while validating this branch's vmlinux bump: a provisioned host with the old release cached silently "passed" E2E on the old kernels.

Validating this bump exposed a cache-invalidation bug:
Provider.install_state/2counted an asset as installed if the file merely existed, so a manifest bump never invalidated the redist cache — provisioned hosts kept booting the previous release's kernels from the same asset paths, silently. A cached file now counts as installed only when its SHA-256 matches the manifest (stale files are re-fetched). Covered by new stale-hashinstall_state/2tests.Test plan
