/**
 * Spawn correlation token: server-minted UUIDv4 per `spawnPiSession` call.
 *
 * Flow: `mintSpawnToken()` → injected into spawned process env as
 * `PI_DASHBOARD_SPAWN_TOKEN` → bridge reads it → bridge echoes back in
 * `session_register.spawnToken` → server links via `linkByToken`.
 *
 * In-memory only; no persistence. TTL aligned to spawn-register-watchdog.
 *
 * See change: spawn-correlation-token.
