rapace-registry: Service registry with schema support for rapace RPC.

This crate provides a registry for RPC services that stores:

• Service names and IDs
• Method names and IDs
• Request/response schemas (via facet shapes)
• Supported encodings per method

Example

use rapace_registry::{ServiceRegistry, ServiceEntry, MethodEntry, Encoding};

let mut registry = ServiceRegistry::new();

// Register services (usually done via macro-generated code)
Adder::register(&mut registry);

// Lookup methods by name
if let Some(method) = registry.lookup_method("Adder", "add") {
    println!("method_id: {}", method.id.0);
}
