1.0.1

Reword the slug-collision message so it explains the refusal rather than referring to a product tier.

No functional change. The message a caller sees when a tag slug is already taken by a real role now says why it is refused:

"%s" is already a real role. A tag cannot shadow one: choose another slug, or delete the role first.
