Wire print_introspection() into both modules with no-args gate per seedgo
introspection standard. Rollover bare command now shows handlers + subcommands
instead of executing. Search bare command shows introspection instead of error.
Fix bug where `search --help` ran a search for "--help". Remove 5 ghost
commands from help text. Restructure rollover as subcommands (run/status/check/
sync-lines).
