Decentralized Identifier (DID) operations for Macula mesh.

This module provides DID document creation, parsing, and verification for the Macula identity hierarchy. It uses Rust NIFs when available, falling back to pure Erlang implementations otherwise.

DID Format

Macula uses the did:macula:` method with hierarchical identities: - Realm: `did:macula:io.macula - Organization: did:macula:io.macula.{org} - Application: did:macula:io.macula.{org}.{app}

DID Document Structure

DID documents follow W3C DID Core specification with Ed25519 keys:

  #{
    <<"@context">> => [<<"https://www.w3.org/ns/did/v1">>],
    <<"id">> => <<"did:macula:io.macula.acme">>,
    <<"controller">> => <<"did:macula:io.macula">>,
    <<"verificationMethod">> => [...],
    <<"authentication">> => [...],
    <<"assertionMethod">> => [...]
