limine-snapper.sh: skip harvest dance when /etc/default/limine is pre-populated

Browse Source 
The ISO orchestrator now writes /etc/default/limine directly from the
install config (with the real cmdline already substituted) before the
chroot phase runs. The previous unconditional find+harvest+copy+sed
sequence would (a) find our orchestrator-staged /boot/limine.conf which
has no `cmdline:` line and (b) exit 1 on "failed to extract kernel
cmdline".

Skip the harvest entirely when /etc/default/limine already exists
without the @@CMDLINE@@ placeholder. Parse CMDLINE from the existing
file so the downstream cryptdevice= validation still has it to compare.

The harvest path remains as a fallback for online reinstalls and any
flow where /etc/default/limine wasn't pre-populated by the orchestrator.
