Claims a single-use value once, for the whole cluster where the store is
shared and for this process otherwise. opts holds scope, value,
ttlMs and realm (the ambient realm by default). Resolves
{ ok: true, handle, claimedAt }, { ok: false, reason: 'used', existing }
or { ok: false, reason: 'store', why }, on which the caller refuses; it
never rejects.
