The host's own run-id mint — context.newRunId() on the run router, the
thread topology's minted id on the agent surface. Run ids are server-minted
and this store never generates one; it only ever stores what it is handed.
A THUNK rather than a value so the store, not the caller, decides when an
id is needed: the caller that loses the insert never uses its candidate,
and a host whose mint is expensive or audited should not pay for one it
throws away. (The mints in this package are pure crypto.randomUUID()
derivations, so a discarded candidate costs nothing and leaks nothing.)
