/**
 * Hedera uses the AccountUpdateTransaction for multiple purposes, including staking operations.
 * Mirror node classifies all such transactions under the same name: "CRYPTOUPDATEACCOUNT".
 *
 * This function distinguishes between:
 * - DELEGATE: Account started staking (staked_node_id changed from null to a node ID)
 * - UNDELEGATE: Account stopped staking (staked_node_id changed from a node ID to null)
 * - REDELEGATE: Account changed staking node (staked_node_id changed from one node to another)
 *
 * The analysis works by:
 * 1. Fetching the account state BEFORE the transaction (using lt: timestamp filter)
 * 2. Fetching the account state AFTER the transaction (using eq: timestamp filter)
 * 3. Comparing the staked_node_id field to determine what changed
 * 4. Calculating the actual staked amount by replaying uncommitted transactions between
 *    the latest balance snapshot and the staking operation to handle snapshot timing mismatches
 *
 * @performance
 * Makes 3 API calls per operation:
 * - account state before
 * - account state after
 * - transaction history based on latest balance snapshot
 *
 * Batching would complicate code for minimal gain given low staking op frequency.
