Populates per-block state read/write counts in slow-block JSON for BAL blocks (which #34892 left as TBD), and adds reader-level read timing. Builds on top of bal-devnet-3 — most of the PR's earlier slow-block log infrastructure was adapted into upstream by that commit, so this change is now scoped to the metric population that the BAL alone can derive. - BAL helpers: BlockAccessList.{UniqueAccountCount, UniqueStorageSlotCount, WrittenCounts}. WrittenCounts walks the BAL once and returns the block-aggregate write counts. - Reader-level read timing: *reader times all synchronous Account/Storage/ Code/CodeSize calls via atomic counters; exposed via ReadTimes() ReadDurations and the new state.ReadTimer interface. Replaces StateDB- level AccountReads/StorageReads/CodeReads tracking (the StateDB shouldn't time its dependencies — the reader is where the I/O happens). - Reader-level code-load dedup: *reader.codeLoaded sync.Map records the first-seen byte length per address; CodeLoads() returns (count, bytes). Exposed via state.CodeLoadTracker. Replaces StateDB CodeLoaded/ CodeLoadBytes tracking and the SnapshotCodeLoads aggregation pattern. - BALStateTransition: caches BlockAccessList.WrittenCounts() once at construction; tracks accountDeleted/storageDeleted atomics for the parallel root-pass (the BAL alone can't distinguish a selfdestruct from a balance/nonce reset). Exposes Deletions() DeletionCounts. Drops the older accountUpdated/storageUpdated/codeUpdated/codeUpdateBytes counters (now derived from WrittenCounts). - BAL block stats path (blockchain.go): populates StateCounts directly — AccountUpdated = WrittenCounts.Accounts - Deletions.Accounts (same for storage). AccountLoaded/StorageLoaded come from BAL. CodeLoaded/ CodeLoadBytes come from the shared *reader (deduplicated across phase StateDBs naturally because they share one reader instance). - Non-BAL block stats path: read durations come from the reader; counts from StateDB fields. StorageUpdated/StorageDeleted unified to int width. - Hard type assertions: state.ReadTimer / state.CodeLoadTracker / state.ReaderStater consumers use direct casts (no silent zero fallback) — every Reader chain in production satisfies these interfaces. - Meter alignment: account/storage Updated meters subtract Deletions to avoid double-reporting blocks under both Update and Delete dashboards.
