Note

Introduce a two-step validator flow with pre-registration and role-gated creation, track validator creation status, add invalidation, and update interfaces/tests.

• Contracts:
  • LiquidityPool (src/LiquidityPool.sol):
    • Add role LIQUIDITY_POOL_VALIDATOR_CREATOR_ROLE and new batchCreateBeaconValidators(...) to send 1 ETH per validator (role-gated) while accounting LP balances.
    • Update staking flow: new step to batchRegister(...) (pre-registration) before creation and funding.
  • StakingManager (src/StakingManager.sol):
    • Track validator state via validatorCreationStatus mapping and emit ValidatorCreationStatusUpdated.
    • Add registerBeaconValidators(...) to pre-register validators (checks bid active, deposit root, node validity) and mark REGISTERED.
    • Gate createBeaconValidators(...) to only REGISTERED entries, then link, deposit 1 ETH, mark CONFIRMED, and update auction info.
    • Add invalidateRegisteredBeaconValidator(...) (role STAKING_MANAGER_VALIDATOR_INVALIDATOR_ROLE) to mark INVALIDATED.
• Interfaces:
  • IStakingManager: add ValidatorCreationStatus enum, new fns registerBeaconValidators(...), invalidateRegisteredBeaconValidator(...), event ValidatorCreationStatusUpdated, and error InvalidValidatorCreationStatus.
  • ILiquidityPool: declare batchCreateBeaconValidators(...).
• Tests:
  • Add test/fork-tests/validator-key-gen.t.sol covering pre-registration, creation, invalidation, role gating, pause checks, accounting, and multi-validator flows.
