draw is single-token (no verb), so `clide draw --file x` mis-parsed as cmd
"draw.--file" — the dispatcher registered draw but the argv parser never
learned it was umbrella (unlike icon/image which use subsystem.verb). Found
driving the live install; the handler unit tests bypassed the argv path so
they missed it. Added draw to _umbrellaCommands + a parse regression test.
