- Switch the default guest kernel from vmlinux-6.18.15-186
(kata-static-3.28.0) to the newer version and variant
vmlinux-6.18.35-197-debug (kata-static-3.32.0).
- The debug variant enables eBPF, kprobes, uprobes, ftrace
and BTF (kata-containers/kata-containers#12567).

Closes https://github.com/apple/container/issues/1687
The default kernel archive is downloaded from a remote release URL
during first-run setup and via `container system kernel set
--recommended`. Previously, the archive contents were not verified after
download, so integrity depended on HTTPS and the release artifact
remaining unchanged.
This change adds digest verification for kernel archives. The
recommended/default kernel now has pinned digest metadata using an
algorithm-prefixed value such as `sha256:<hex>`. `container system
kernel set --tar` accepts `--digest`; remote tar URLs require it, and
local tar archives can also be verified before unpacking and
installation.
The system config also supports `kernel.digest`, and a custom
`kernel.url` must provide a digest for that archive.
