feat: add multi-node blockchain monitoring workflows for 3-node network
- Create multi-node blockchain health monitoring workflow - Create P2P network verification workflow for all 3 nodes - Create blockchain synchronization verification workflow - Update blockchain-communication-test.sh to include aitbc2 (gitea-runner) - Add shared scripts directory with health check, P2P verification, and sync verification scripts - All workflows trigger on git push to main/develop branches - Workflows run on gitea-runner (has SSH access to all nodes) - Include automatic remediation for failed services and sync issues - Sync threshold set to 10 blocks - Logging to /var/log/aitbc/ and alerts in Gitea UI
