Solutions

1. Remove one of the two channel flags
2. Set the desired channel once via config and omit flags

Example fix

# before
omx update --stable --dev
# after
omx update --stable

const has = (f: string) => args.includes(f);
if (has('--stable') && has('--dev')) throw new Error('mutually exclusive');

When it happens

Trigger: `omx update --stable --dev` (in any order).

Common situations: Copy-paste accumulation of flags; scripts combining a default channel with a user override.
