Crate nodedb_types 

Shared NodeDB type definitions: strong IDs (TenantId, VShardId, RequestId, Lsn, Surrogate), error types (NodeDbError + ErrorCode + ErrorDetails), wire types for cross-plane and cross-node messages, value types, configuration schemas, and the approximate-aggregate sketches.

Every NodeDB workspace crate depends on this. Items here form the stable cross-crate vocabulary; types specific to one engine live in that engine’s crate.
