Initial commit: Lux Graph Engine

Browse Source 
Single-binary GraphQL query layer replacing The Graph's Graph Node.
SQLite WAL + hanzoai/replicate S3 streaming + luxfi/age PQ encryption.

- 18 schemas: AMM V2/V3/V4, DEX, FHE, Platform, XChain, Bridge,
  Privacy, Quantum, Key, AI, Identity, Oracle, Relay, ServiceNode,
  Precompile, ERC20, ERC721
- WASM subgraph loader (uni-v2/v3/v4 build/ dirs)
- EVM indexer: eth_blockNumber + eth_getLogs + V2/V3/V4 event decoding
- Production hardened: rate limiter, query depth/field caps,
  MaxBytesReader, structured logging, /ready, /metrics
- 32 e2e tests, 13 benchmarks, 775 qps @ 100 clients on SQLite
- Dockerfile (multi-stage CGO, non-root, healthcheck)

// graph -- standalone GraphQL query layer for any EVM chain.
//
// Connects to an RPC endpoint, indexes events into local SQLite/ZapDB,
// serves a GraphQL API compatible with The Graph subgraph queries.
// Also runs as a Lux VM (G-Chain) when loaded by luxd as a plugin.
//
// Standalone:
//
// graph --rpc=http://node:8545 # any EVM
// graph --rpc=http://node:9650/ext/bc/{chainID}/rpc # any Lux subnet
// graph --config=subgraphs.yaml # multi-subgraph
// graph --rpc=http://node:8545 --schema=uniswap-v2 # specific schema
//
// Scale horizontally: run N graph nodes behind a load balancer.
// Each indexes independently into its own local storage.

// Package wasm provides a subgraph execution runtime using wazero.
//
// Loads compiled AssemblyScript WASM modules from `graph build` output,

// log.log, etc.), and executes event handlers against incoming EVM logs.

// Usage:
//
// rt, _ := wasm.NewRuntime(ctx)
// sg, _ := rt.LoadSubgraph("./uni-v2-subgraph/build/")
// sg.HandleEvent(log) // executes the AS mapping handler
// entities := sg.Flush() // returns modified entities for storage
