9// DONE Process unstake requests.
10//      For each "unstake request" transfer tokens from the Worker stake account to the Delegation authority's token account.
11//      Decrement the Delegation's stake balance by the amount unstaked.
12
13// DONE Lock delegated stakes.
14//      Transfer tokens from the Delegation's stake account to the Worker's stake account.
15//      Increment the Delegation's stake balance by the amount moved.
16
17// DONE Take a snapshot.
18//      Capture a snapshot (cumulative sum) of the total stake and broken-down delegation balances.
19//      SnapshotFrames capture worker-level aggregate stake balances.
20//      SnapshotEntries capture delegation-level individual stake balances.
