Streamlining On-Chain Event Subscriptions

The latest refactor in core/tools/buildinpublic.py and phases/phase4content.py addresses a major bottleneck in how our modules ingest live on-chain swap activity. Standard HTTP/WebSocket polling against public JSON-RPC nodes was introducing intermittent timeouts and packet drops during high-volume contract deployments (which happens constantly when parsing rapid pool creation).

Key Architectural Shifts

gRPC over JSON-RPC: Replaced the legacy WebSocket listener with a dedicated gRPC subscription pipeline. This drops serialization overhead and ensures deterministic event ordering.

Decoupled Parsing Logic: Shifted the mutation tracking out of the primary ingestion thread. The content generation engine in phase4content.py now consumes from an internal lock-free ring buffer.

Idempotency Filters: Added an aggressive instruction-data filter (verifyinstructiondata) at the edge to instantly drop noise and failed transactions before they hit the memory layer.

The fallback mechanism handles immediate reconnects without dropping state (a critical fix since flaky network layers were corrupting our automated historical logs). The pipeline now processes throughput spikes with a minimal memory footprint, ensuring the data layer stays perfectly synchronized with state changes on-chain.
