Pass the first pivot, stored in ChainSyncState and persisted in ChainSyncStateStorage, through SnapSyncProcessState to SnapWorldDownloadState (+ make sure to preserve it when recreating SnapSyncProcessStatein SnapSyncDownloader#storeState) where it is used in checkCompletion to decide whether BAL requests should be enqueued. Due to dependencies between request queues, enqueueing BAL requests blocks flat db requests. This means that BALs are applied (when necessary) strictly after trie healing and before flat db healing phase. Moreover, BAL request enqueuing is gated behind AtomicBoolean (+ checkCompletion is synchronized) to happen only once.

Batched BAL responses are then passed through PersistDataStep#persist to BlockAccessListDataRequest#doPersist where they are applied to the provided BonsaiWorldStateKeyValueStorage.Updater and later committed to storage. We make sure to recompute the storage root if any slots were modified.

Some functionality shared with BalStateRootCalculator (where BALs are applied to world state in a similar way) was extracted to BlockAccessListChanges. This results in extra copy - not sure about performance impact.

Follow up PR will introduce a functionality to the Pipeline which will allow to aggregate batches of items into a single batch, so that all changes from BALs are applied to the same updater and committed in one atomic operation.

if we keep all the pivot blocks used during snapsync you can completely skip the fladb healing if all the pivot blocks used are canonical and only trigger the heal if one of the block is not canonical

Not necessarily all pivots, as we already discussed. It's a valid point but hopefully you don't want to address it in this PR :)

in another PR I think it will be better to download the BAL before in the pipeline where we are downloading header, body

* Improve block proposal cancellation to (best effort) avoid concurrency issues (#10219)

* Fix concurrency issues when block proposal is cancelled during tx selection

When block creation is cancelled or times out, the selection thread may still
be running briefly. This change adds a CountDownLatch to internal tx selection
(mirroring the existing plugin selection mechanism) and extracts a shared
waitForCancellationToBeProcessed method that correctly handles negative
remaining-time values and logs the outcome of the wait.

Exception handling in both selection phases is split by type so that
rollback() is only called for ExecutionException, where the selection thread
is guaranteed to have finished. CancellationException and InterruptedException
no longer trigger a rollback, removing a potential race on shared world state.

In MergeCoordinator, exceptions thrown after a cancellation are now logged at
INFO with guidance to report if unexpected, rather than at WARN, reducing noise
from the expected concurrency edge cases during block proposal cancellation.

* Add unit tests for concurrency fixes and repair early-return regression

- Add test verifying CancellationException during plugin selection is
  handled gracefully (no exception propagated to caller)
- Add test verifying internal selection CountDownLatch causes
  buildTransactionListForBlock() to wait for the selection thread
- Add test verifying Throwable thrown after block creation cancellation
  is handled gracefully (logged at INFO, not propagated)
- Remove early return from timeLimitedSelection when isCancelled is
  true: the guard was causing validPendingTransactionIsNotIncludedIf
  SelectionCancelled to fail because evaluatePendingTransaction (which
  marks each tx as SELECTION_CANCELLED) was never reached; the check
  is unnecessary since evaluatePendingTransaction already handles
  isCancelled on every iteration without touching world state

* Remove dryRunDetector workaround methods from unit tests

The dryRunDetector methods were added as a workaround for a Gradle issue
that prevented @ParameterizedTest classes from being selected when running
with --dry-run. Since the issue is fixed and --dry-run is no longer used,
these methods are no longer needed.

* Remove dryRunDetector workaround from acceptance tests too

The Gradle issue is confirmed fixed, so the workaround is no longer
