Implement interface for publishing encrypted records to distributed storage

[veryCrunchy]

Design and implement a Rust trait and module for publishing encrypted uptime/downtime records to the chosen distributed backend (e.g., IPFS or libp2p DHT). The interface should:

• Accept already-encrypted records as input (struct EncryptedRecord).
• Upload (publish) records to the network, returning a unique content-addressed hash (CID).
• Support metadata for lookup (e.g., tags, timestamps, node ID).
• Abstract over specific backends for easy swapping (e.g., IPFS, libp2p DHT).
• Include unit/integration tests using mock or local IPFS nodes.

Implementation Suggestions:

• Define a trait DistributedStorage with async methods: publish, fetch, pin, unpin.
• Use crates: ipfs-api, rust-libp2p, or rust-ipfs.
• Use serde for serialization.
• Ensure all data remains encrypted in transit/storage.
