* fix: update code for signet-types 0.16.0-rc.11 API changes

Adapt to breaking changes in signet-types and signet-extract rc.11:
- SealedBlock now takes 1 generic param (transaction type only)
- SealedBlock uses `header`/`transactions` fields (no more `body`)
- RecoveredBlock is now SealedBlock<Recovered<TransactionSigned>>
- SealedHeader is now Sealed<Header> (use .inner()/.seal() instead of .header()/.hash())
- HasTxns::transactions() returns impl ExactSizeIterator instead of &[T]
- RecoveredBlock.senders() is now a method returning an iterator

* chore: bump reth v1.10.2 to v1.11.0

Adapt to breaking changes in reth v1.11:
- ProviderFactory::new takes a Runtime argument
- TaskSpawner::spawn -> spawn_task, spawn_critical -> spawn_critical_task
- MINIMUM_PRUNING_DISTANCE -> MINIMUM_UNWIND_SAFE_DISTANCE
- StorageEntry -> ChangesetEntry in unwind_storage_history_indices
- Tx.inner field is now private (use .inner() method)
- ProviderFactory::new_with_database_path returns DatabaseEnv (not Arc)
- StaticFileSegment::StorageChangeSets new variant
- check_segment_consistency is now private

* feat(node): add configurable backfill thresholds (ENG-1919)

Add BACKFILL_MAX_BLOCKS config option to control memory usage during sync.
Default is 10,000 blocks per batch (reth's 500K default causes OOM on mainnet).

Changes:
- Add backfill_max_blocks field to SignetNodeConfig
- Add accessor with 10K default
- Configure ExecutionStageThresholds after set_with_head calls
- Add set_backfill_thresholds helper method

* fix(node): add missing reth-stages-types dep and fix mutability

The `reth_stages_types` crate was used but not declared as a dependency,
and `set_backfill_thresholds` needed `&mut self` to mutate notifications.

* fix(node): Set backfill max job duration to a safe amount of time

Our timeout crash is caused by a footgun on Reth's backfill threshold configuration API. Here's how it roughly looks:
- reth allows the mdbx tx timeout sentinel thread to have a configurable max timeout, hidden behind a flag (--db.read-transaction-timeout). We currently, AFAIK, do not configure this. The default value is 5 minutes. Any transactions that live beyond that are killed.
- Reth, for the exex backfill, sets the max_duration for its backfill processes to 30 seconds. This does not exceed the default max timeout for the mdbx sentinel thread.
- The `ExecutionStageThresholds` default for max duration for execution jobs is 10 minutes. This, by far, exceeds the mdbx timeout sentinel thread max duration. On the execution stage for the reth node this is safe as it calls `disable_long_read_transaction_safety()`, which bypasses the timeout. This is not done on backfill, so this default is unsafe. This is therefore a massive footgun for any exex that configures backfill thresholds.
- We were only tweaking the `max_blocks` config value, and using the unsafe default for max duration, when setting the backfill thresholds. This leads to us avoiding an OOM crash, but then running into an mdbx crash due to the sentinel thread forcibly killing the transaction.
- Before `set_backfill_thresholds` was added, what caused the OOM was the massive amount of blocks being processed. `max_duration` had a sane default (30s). Once it was introduced, this new bug was added due to the `::default()` usage.
- The fix, is therefore, to limit the max duration to a reasonably low time. 30s should be fine.
  - Note: 30s is a reasonably margin due to a few reasons:
    - We avoid the hard 5m timeout.
    - The intended default for exex backfill was already 30s.
    - There's a 60s timeout warning already, this avoids it entirely. We've seen this error spuriously over the entirety of the signet node's lifecycle.

… configure_notifications (#92)

The two calls were always paired across 4 call sites in set_exex_head.
Bundling them into a single helper eliminates the risk of forgetting to
pair them when adding new code paths.

Move AliasOracleFactory::create() out of the per-address should_alias
helper and into run_evm, so all addresses in a block share the same
host state snapshot. Expand the comment in create() with a full
correctness analysis of why Latest is safe.
