Add node-facts.sh script with JSON node facts emission
Implements node-facts.sh that emits JSON documents for monitoring and inventory: - Reads COMPOSE_FILE from .env and iterates only those compose files - Fails fast with JSON error when .env missing or COMPOSE_FILE empty (exit 2) - Uses --max-time for all curl calls (5s general, 10s for peers) - Bounded parallel worker count for node processing - Supports avalanchego, op-node/kona, beacon REST, geth-family, besu, reth/op-reth - Includes fixture-only test-node-facts.sh with schema validation - Adds README entry for the new script Generated by Mistral Vibe.
