Extend DB benchmark to support state store (SS) backends#2995
Conversation
Add SSPebbleDB and SSComposite backend types so the existing ERC20 benchmark can drive the historical state store using the same changeset write path. Made-with: Cursor

The latest Buf updates on your PR. Results from workflow Buf / buf (pull_request).

Add a combinedWrapper that fans out changeset writes to both a State Commit and State Store backend, mirroring production. Two new backend types: FlatKV+SSPebble and CompositeDual+SSComposite. Made-with: Cursor

Verifies SSPebbleDB and FlatKV+SSPebble work with the existing runBenchmark harness (version tracking, changeset generation, etc). Made-with: Cursor
SSPebbleDB bypassed the SS layer (Tier 2) and hit raw PebbleDB MVCC directly - not a real production path. All SS backends now go through CompositeStateStore, matching the architecture. Extracted shared openSSComposite helper to deduplicate SS creation. Made-with: Cursor
Drop FlatKV+SSComposite since the production path is CompositeDual+SS. Fix combinedWrapper version tracking to use SS version (consistent across all SC backends). Made-with: Cursor

LGTM once the config file is fixed.
I like how low-touch this ended up being... I was initially concerned that this would result in a big diff inside the benchmark that would conflict with my in-flight branches. So only seeing a new wrapper is a relief. 😅

Extend cryptosim DB benchmark to support state store (SS) backends via a lightweight StateStore → DBWrapper adapter
Adds SSPebbleDB (raw MVCC) and SSComposite (full CompositeStateStore with EVM sub-DB routing) so the same ERC20 changeset workload can benchmark the historical state store
Suppports mode for SC + SS
