fix(cliproxy): show global help regardless of flag order before --help

Top-level cliproxy help was order-sensitive: 'cliproxy --verbose --help' fell
through to dispatch instead of showing help. Fire global help whenever there is
no real subcommand (no args or a leading flag) and --help/-h appears anywhere;
real subcommands still handle their own --help.
