/**
 * Port interface for seek materialization cache operations.
 *
 * Defines the contract for caching and retrieving serialized WarpState
 * snapshots keyed by (ceiling, frontier) tuples. Used by the seek time-travel
 * feature to avoid full re-materialization for previously-visited ticks.
 *
 * Concrete adapters (e.g., CasSeekCacheAdapter) implement this interface
 * to store cached states in different backends (git-cas, filesystem, etc.).
