Move the top-level usage/command-list text out of the dispatcher into commands/help.py as cmd_help, registered in COMMANDS so `bb help` now works as a real command. The dispatcher's -h/--help, no-args, and unknown-command fallbacks call cmd_help() for the text while keeping their exit codes (0 for help/-h, 2 for bare no-args, Die for unknown). Added `help` to NO_MIGRATION_COMMANDS so it prints without a migrated DB, and listed it in the command summary. Full unit suite green (2243); dispatch + migration-gate tests pass, `bb help` verified.
