Crate cow_errors 

cow-errors — shared error type for the CoW Protocol SDK.

CowError is the unified error type used across the workspace. Every fallible function in the SDK currently returns Result<T, CowError>.

Per architecture rule 8 (errors per-domain + aggregation), this crate is a migration stopgap: future phases will split CowError into per-crate error types (SigningError, OrderbookError, …) and aggregate them via a façade-level SdkError.
