feat: RandomX PoW, LWMA difficulty, stratum mining.* protocol, new genesis 
Replace ProgPowZ with RandomX for ASIC-resistant proof-of-work. The
full dataset is initialized multi-threaded at startup with the key
"LetheanRandomXv1". Thread-local VMs are created on demand.

Switch difficulty algorithm from Zano's 720-block window to LWMA-1
(zawy12) with a 60-block window for much faster convergence after
hashrate changes. Target block time set to 10s for PoW.

Add standard stratum mining.* protocol handlers (subscribe, authorize,
submit, extranonce.subscribe) alongside existing EthProxy eth_*
handlers, with automatic protocol detection and mining.notify
translation for XMRig-based miners.

Generate fresh Lethean genesis block and premine wallet. Replace all
remaining hardcoded Zano addresses in tests with runtime-generated
keys to avoid prefix mismatches. Link RandomX library across all
build targets.
