feat: Add multi-node P2P mining management system

Implement secure peer-to-peer communication between Mining CLI instances for remote control of mining rigs. Uses Borg library for encryption (SMSG, STMF, TIM) and Poindexter for KD-tree based peer selection. Features: - Node identity management with X25519 keypairs - Peer registry with multi-factor optimization (ping/hops/geo/score) - WebSocket transport with SMSG encryption - Controller/Worker architecture for remote operations - TIM/STIM encrypted bundles for profile/miner deployment - CLI commands: node, peer, remote - REST API endpoints for node/peer/remote operations - Docker support for P2P testing with multiple nodes 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
