Pull Request Overview

Adds support for a Decentralized Message Queue (DMQ) node across end-to-end tests, relay components, signers, aggregators, and the mithril-dmq crate.

• Introduce DMQ_NODE_SOCKET_PATH env var and socket setup in end-to-end signer and aggregator.
• Extend relay components and CLI commands to accept DMQ socket path and Cardano network settings.
• Refactor mithril-dmq crate to split client/server interfaces and enable future_dmq by default.

• [nitpick] End-to-end tests don’t currently cover the DMQ_NODE_SOCKET_PATH setup. Add tests that exercise DMQ-based workflows to verify this new configuration is applied correctly.
