The capability identifier (NSID + arity) of a tag. Extracted from our own Tag/
MultiTagS parameter rather than via Effect's Context.Service.Identifier, which — for a
generic tag parameter — falls through to its TagClassShape branch and yields the raw tag
(leaking the service type again). Singleton checked first; a singleton never matches the multi
arm and vice versa (the arity brand differs).
