/**
 * get_historical_state Tool
 *
 * Returns the vault's `HistoricalVaultState` at a specific Unix timestamp
 * via `Vault.stateAt(timestamp)`. Far simpler than reconstructing state from
 * the event stream.
 *
 * Use cases:
 * - "What was the price per share on date X?"
 * - "What were the fees at vault inception vs today?"
 * - "Was the vault paused at the time of incident Y?"
 *
 * Cache: cacheTTL.historicalState (60 minutes — historical state by
 * timestamp is immutable once past).
 *
 * Cache tag: vault-adjacent. Registered under CacheTag.VAULT.
