Expand description

Unified maintenance task for the Tempo transaction pool.

Handles:

  • Evicting expired AA transactions (valid_before <= tip_timestamp)
  • Evicting transactions using expired keychain keys (AuthorizedKey.expiry <= tip_timestamp)
  • Updating the AA 2D nonce pool from NonceManager changes
  • Refreshing the AMM liquidity cache from FeeManager updates
  • Removing transactions signed with revoked keychain keys
  • Moving transactions to/from the paused pool when fee tokens are paused/unpaused

Consolidates these operations into a single event loop to avoid multiple tasks competing for canonical state updates and to minimize contention on pool locks.
