Crate reddb_types 

reddb-io-types — the neutral keystone crate for RedDB’s logical type system (ADR 0052).

This crate sits at the bottom of the workspace crate graph: every authority crate (reddb-io-file, reddb-io-wire, the planned reddb-io-rql and reddb-io-crypto) may depend on it, but it depends on no other workspace crate. It owns the core type vocabulary — Value, DataType, SqlTypeName, TypeModifier, TypeCategory, ValueError, and Row — together with the value_codec serialization that Value::to_bytes/from_bytes delegate to.

The reddb-server storage::schema module no longer re-exports this vocabulary; every server, test, and driver call site names this crate directly.
