feat: NO_PARALLEL_DEPLOYMENT

[gzeoneth]

POC, dirty hack; should pass isSerialDeployment into internal methods instead of reading from env everytime

[Copilot]

Pull Request Overview

This PR adds a “NO_PARALLEL_DEPLOYMENT” feature flag to switch between parallel and serial contract deployments, introducing a deployBatch helper and mutex locking for serial mode.

• Introduces deployLock and refactors deployment flows to respect the NO_PARALLEL_DEPLOYMENT env var.
• Adds a deployBatch helper to sequence or parallelize deployment functions.
• Updates deployContract, create2, deployAllContracts, and deployOneStepProofEntry to use serial/parallel logic.

• [nitpick] The local variable useSerialDeployment is named differently from isSerialDeployment used elsewhere. Consider unifying this to a single name for consistency.

    const useSerialDeployment = process.env.NO_PARALLEL_DEPLOYMENT === 'true'

• [nitpick] The new deployBatch helper implementing serial vs. parallel flows is not covered by existing tests. Adding unit tests or integration tests for both modes will help prevent regressions.
