/**
 * An identity whose private key script cannot read, or `null` where the platform
 * cannot provide one.
 *
 * Returns `null` rather than throwing, and rather than quietly handing back a
 * weaker implementation, because those are the two ways a caller ends up
 * believing it has a guarantee it does not have. A `null` here means: this engine
 * cannot do it, carry on with the ordinary path and know that you did.
 *
 * Two separate conditions are checked, and both matter. `isSupported` asks
 * whether the primitive exists. `canPersist` asks whether a key survives being
 * stored and read back, which WebKit fails for X25519 while reporting the write
 * as successful. An identity that silently regenerates every load makes every
 * previous conversation undecryptable, with nothing raised to explain it, so the
 * check is worth its round trip.
 *
 * Migration is the caller's to trigger, via `migrateFromKeyStorage`, because it
 * removes the raw key and that is not a decision to take on someone's behalf.
