Add ringtail post-deploy maintenance: kernel check, generation pruning, GC

Update manage-lockfile doc with post-deploy steps (kernel update detection,
reboot guidance, generation pruning). Add prune-ringtail-generations mise
task that keeps the 5 most recent generations plus the most recent one
matching the booted kernel for safe rollback.
