feat: add LinkSwarm settlement orchestrator with Chainlink Functions verification

[Jsand-187]

LinkSwarm: Chainlink Functions-Gated Settlement Orchestrator

Overview

LinkSwarm is a production-ready settlement engine that uses Chainlink Functions as the mandatory verification gate for every batch settlement.

Key Features

• Functions as Gate: No settlement occurs until Functions verifies the commitment
• High Throughput: Designed for 10,000+ workers per batch
• Multi-Network: EVM, Solana, Cosmos, UTXO delivery after verification
• Private Ledgers: Per-user immutable history with audit trail
• USDC/Fiat Bridge: Automatic conversion with dual-hash accounting
• Full Reports: JSON + CSV with chainlinkVerified and functionsRequestId

Architecture

Worker Batch → Entropy-3.12 Commitment → Chainlink Functions (gate) → Delivery Adapters → Private Ledgers → Reports
