Error Handling:
- Fix silent Write() error in WebSocket (events.go)
- Add error context to transport handshake messages
- Check os.MkdirAll error in zip extraction (miner.go)
- Explicitly ignore io.Copy errors on drain with comments
- Add retry logic (2 attempts) for transient stats collection failures
Resource Lifecycle:
- Add shutdown mechanism to DigestAuth goroutine
- Call Service.Stop() on context cancellation
- Add NodeService transport cleanup to Service.Stop()
- Fix WriteStdin goroutine leak on timeout with non-blocking send
API Design:
- Add profile validation (name, miner type required)
- Return 404 instead of 500 for missing profile PUT
- Make DELETE profile idempotent (return success if not found)
- Standardize error responses in node_service.go handlers
Observability:
- Add logging for P2P GetAllStats failures
- Add request ID correlation helper for handler logs
- Add logging for miner process exits (xmrig_start.go)
- Rate limit debug logs in transport hot path (1 in 100)
- Add metrics infrastructure with /metrics endpoint

Implement GPU mining backends for three new algorithms:
- ProgPowZ (Zano): DAG-based ProgPow variant with 512 parents, dynamic
program generation per period
- ETChash (Ethereum Classic): Standard Ethash with 256 parents and
ECIP-1099 epoch calculation for post-block 11.7M
- Blake3DCR (Decred): Simple Blake3 hash kernel with no DAG requirement,
processing 180-byte block headers
Each implementation includes OpenCL kernels, GPU runners, thread
generators, and build system integration. Also adds fast modulo
optimization to ETCCache for GPU kernel performance.

- Add GPU config fields: GPUEnabled, GPUPool, GPUWallet, GPUAlgo, CUDA, OpenCL
- XMRig config now supports separate pool/algo for GPU vs CPU mining
- CPU can mine RandomX while GPU mines KawPow on different pools
- Add xmrig_gpu_test.go with tests for dual, GPU-only, and CPU-only configs
- Make getXMRigConfigPath a variable for test overriding
