summary: Check that command-chain is properly supported
details: |
Verify the command-chain feature works as expected for hooks, apps, and
services. Rather than running the hook, app, or service directly, the
command-chain should be prefixed to the target command. Additionally verify
that the command-chain is executed when running a snap with `snap run
--shell`.

# Ensure that running purely from the deb (without re-exec) works
# correctly
