myko 4.10.0

//! # Myko RS - Event-Sourcing CQRS Framework
//!
//! `myko` is an actor-based event-sourcing framework for building real-time,
//! distributed systems with strong consistency guarantees.
//!
//! ## Core Concepts
//!
//! | Concept | Description |
//! |---------|-------------|
//! | **Item** | Base entity with typed `id` |
//! | **Event** | Immutable record of state change: `SET` (create/update) or `DEL` (delete) |
//! | **Query** | Request for live data stream, returns reactive `Observable<T[]>` |
//! | **Report** | Computed/derived data request, returns `Observable<T>` |
//! | **Command** | Intent to mutate state, returns result of operation |
//! | **Saga** | Stateful stream processor that reacts to events and emits commands |
//!
//! ## Architecture

//! ```
//!
//! ## Quick Start
//!
//! Define an entity using the `#[myko_item]` attribute macro:
//!
//! ```text
//! use myko::prelude::*;
//!
//! #[myko_item]
//! pub struct Target {
//!     pub name: String,
//!     pub category: Option<String>,
//!     // id is added automatically
//! }
//! ```
//!
//! The macro auto-generates:
//! - `GetAllTargets`, `GetTargetsByIds`, `GetTargetsByQuery` queries
//! - `CountAllTargets`, `CountTargets`, `GetTargetById` reports
//! - `DeleteTarget`, `DeleteTargets` commands
//! - `PartialTarget` struct for partial matching
//! - Registration with the [`inventory`] system
//!
//! ## Module Guide
//!
//! | Module | Purpose |
//! |--------|---------|
//! | [`client`] | WebSocket client for connecting to Myko servers |
//! | [`core`] | Core types: command, query, report, saga, item, relationship |
//! | [`wire`] | Wire protocol types: MykoMessage, MEvent, responses, errors |
//! | [`server`] | CellServer and server context |
//! | [`store`] | Entity store and registry |
//!
//! ## Performance
//!
//! Myko-rs is optimized for high-throughput, low-latency scenarios:
//!
//! - **Hyphae cells**: Reactive queries and reports using the hyphae cell library
//! - **Lock-free stores**: CellMap for concurrent entity access
//! - **MessagePack serialization**: Binary format for efficient WebSocket communication
//! - **Pluggable persistence**: Run in-memory for development, add Postgres for production persistence
//!
//! See `libs/myko/rs/OPTIMIZATION.md` for detailed performance guidelines.
