Rename NEO to Annos and GAS to Lub native contracts

Rename the core governance and utility tokens to reflect Tutus blockchain's identity-centric design: - NEO -> Annos (Latin for "years" - governance token tied to Vita) - GAS -> Lub (lubrication - utility/fee token) File renames: - native_neo.go -> native_annos.go - native_gas.go -> native_lub.go - native_neo_candidate.go -> native_annos_candidate.go Struct/interface renames: - NEO struct -> Annos, INEO -> IAnnos - GAS struct -> Lub, IGAS -> ILub Constants updated: - nativenames: Neo="NeoToken" -> Annos="AnnosToken" - nativenames: Gas="GasToken" -> Lub="LubToken" - NEOTotalSupply -> AnnosTotalSupply - GASFactor -> LubFactor Regenerated nativehashes for new manifest names. Updated all native contracts, blockchain.go, test files, CLI wallet, and RPC client packages. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
