release: Reduce allocation configuration delay & min withdrawal delay on Holesky

[solimander]

Motivation:

• The current delays on Holesky testnet are too lengthy for efficient testing:
  • ALLOCATION_CONFIGURATION_DELAY: 75 blocks (~15 minutes)
  • DEALLOCATION_DELAY: 50 blocks (~10 minutes)
  • MIN_WITHDRAWAL_DELAY_BLOCKS: 50 blocks (~10 minutes)
• This release reduces these delays to enable faster iteration and testing:
  • ALLOCATION_CONFIGURATION_DELAY: reduced to 30 blocks (~6 minutes)
  • DEALLOCATION_DELAY: 25 blocks (~5 minutes)
  • MIN_WITHDRAWAL_DELAY_BLOCKS: reduced to 25 blocks (~5 minutes)

Modifications:

• Added a new release folder script/releases/v1.4.2-testnet-delay-reduction/:
  • 1-deployContracts.s.sol – Deploys fresh AllocationManager and DelegationManager implementations, with the lowered ALLOCATION_CONFIGURATION_DELAY and MIN_WITHDRAWAL_DELAY pulled from Env.
  • 2-queueUpgrade.s.sol – Queues the upgrade transaction via the multisig and TimelockController.
  • 3-executeUpgrade.s.sol – Executes the queued upgrade transaction via the multisig and TimelockController after the timelock delay.
  • upgrade.json – Defines the three-phase release (eoa, multisig queue, multisig execute) for Zeus, coordinating the execution of the scripts above.

Result:

• The AllocationManager & DelegationManager proxy contracts on Holesky will be upgraded to point to the newly deployed v1.4.2 implementation.
• This new AllocationManager implementation incorporates the reduced ALLOCATION_CONFIGURATION_DELAY and MIN_WITHDRAWAL_DELAY (values determined by the Holesky environment variable).
• This new DelegationManager implementation incorporates the reduced MIN_WITHDRAWAL_DELAY (value determined by the Holesky environment variable).

Notes:

This is a testnet-only upgrade.

LGTM, will wait for someone on protocol to approve as well

Also need to update AllocationManager.md with these delays: https://github.com/Layr-Labs/eigenlayer-contracts/blob/main/docs/core/AllocationManager.md#parameterization

Also I think the README has a typo?

Configuration Delay should be 6 mins. Withdrawal delay should be 5 minutes
