fix(setup): prevent offline bootstrap from intercepting sync/backup/restore subcommands

The try_bootstrap_from_offline_package call at line 2138 ran before subcommand
routing (sync/backup/restore/migrate/uninstall) at line 2357+, causing those
subcommands to be silently consumed by the offline bootstrap early-exit path.

Added a case guard to skip the offline bootstrap when a recognized subcommand
is provided as $1.
