WalkthroughStartDB now requires a uint32_t shard_id parameter; the DataStore interface and EloqStoreDataStore signature were updated (default 0). Call sites updated to pass data_shard_id. A new eloq_store_max_global_request_batch flag was added and initialized. The eloqstore submodule pointer was updated. Changes

Update RocksDBDataStore and RocksDBCloudDataStore signatures to match the base interface.
The change at line 428 correctly passes shard_id to StartDB, but two critical implementations have incorrect signatures that violate the base class contract:
RocksDBDataStore::StartDB(int64_t term)- should acceptuint32_t shard_idparameterRocksDBCloudDataStore::StartDB(int64_t term)- should acceptuint32_t shard_idparameter
The base class interface defines: virtual bool StartDB(int64_t term, uint32_t shard_id) = 0;
This will cause method resolution failures when factories for these implementations (rocksdb_data_store_factory.h, rocksdb_cloud_data_store_factory.h) create and initialize data stores from line 428.

Update RocksDBDataStore and RocksDBCloudDataStore to match the new StartDB signature.
The base class signature changed to StartDB(int64_t term, uint32_t shard_id), but rocksdb_data_store.h:51 and rocksdb_cloud_data_store.h:65 still declare StartDB(int64_t term) override. The corresponding definitions in .cpp files also use the old signature. This mismatch breaks the override contract and causes compilation failure. Update both the header declarations and .cpp implementations in both files.

Remove the default argument from StartDB override to match the base class interface.
Line 180 has data_shard_id = 0 only in the derived override, while DataStore::StartDB defines the parameter without a default. In C++, default arguments are statically bound, so this inconsistency allows one-argument calls that would violate the base class contract and weaken explicit shard propagation.
