Shared vocabulary types and traits for the EventCore event sourcing library.

This crate provides the foundational types that are shared between the main eventcore crate and adapter implementations like eventcore-postgres. By extracting these types into a separate crate, we enable feature flag-based adapter re-exports without circular dependencies.

Overview

This crate contains:

• Core traits: Event, EventStore, CommandLogic, CommandStreams, StreamResolver
• Domain types: StreamId, StreamVersion, StreamWrites, StreamWriteEntry
• Event handling: EventStreamReader, EventStreamSlice, NewEvents
• Command types: StreamDeclarations, StreamDeclarationsError
• Errors: EventStoreError, CommandError, Operation
