Seed the subflow's GlobalStore with initial values.
Called before subflow execution to make inputMapper values available.
Redaction: the seed is committed as the subflow's history[0] by its root
context. SubflowExecutor installs the run's redaction rule on that context
before calling this, so the commit retains under the policy (9.19.0).
mount names the seed bundle: the engine passes the MOUNT's frame, because
the mount is the stage whose inputMapper produced the seed (R13).
