November 2024: Shopify/tidb monthly summary. Delivered central bootstrap status management in storage by removing the sessionBootstrapped flag and using kv.Storage SetOption/GetOption to centralize bootstrap state.

These changes reduce bootstrap state drift, improve correctness of enum update paths, and expand test coverage.
