Returns true iff grant covers claim — the claim asks for the same
or less authority. Used at draft creation (claim vs session grant) and
merge time (manifest claim vs ref policy).
Selector logic: a grant without a selector covers any selector; a grant
with a selector requires the claim to be at least as narrow (claim type
within grant type pattern, claim carrying every grant constraint with
an equal value).
