Initialize PR documentation for Ethereum Transaction Observatory

[Copilot]

The repository needed a PR to document the current implementation state of the Ethereum Transaction Observatory - a custom node for mempool transaction monitoring.

Current Implementation

Core P2P Stack

• discv4 node discovery
• RLPx handshake and frame exchange
• Session management for up to 1000 peers
• Block relay via Alchemy WebSocket integration

Transaction Monitoring

• Gossip transaction reception and decoding
• Lifecycle statistics tracking (arrival → inclusion/drop)
• Pending transaction retrieval from Alchemy

Configuration

• Network: Ethereum mainnet (network_id: 1)
• Ports: UDP/TCP 33333
• Max peers: 1000

Known Gaps

• Block coverage: ~20% (target: 80%)
• Sampling bias: Only receives transactions from peers, not users
• Peer behavior optimization needed to maintain connections
