Plug-in artifact identity and boundary primitives for
[NautilusTrader](https://nautilustrader.io).

The `nautilus-plugin` crate provides the public contract that lets an independently compiled Rust
cdylib identify itself to a Nautilus host. It defines versioned build metadata, allocator-safe
boundary values, opaque host tokens, and the `nautilus_plugin!` macro for exporting the standard
entry symbol and manifest.

This crate gives hosted artifacts a consistent identity and a compact contract for Nautilus deployments.

## NautilusTrader

[NautilusTrader](https://nautilustrader.io) is an open-source, production-grade, Rust-native
engine for multi-asset, multi-venue trading systems.

The system spans research, deterministic simulation, and live execution within a single
event-driven architecture, providing research-to-live semantic parity.

## Feature flags

This crate provides feature flags to control source code inclusion during compilation:

- `host`: Retains compatibility with host-enabled plug-in manifests.
