feat(chain): GNX 代币经济模型 — 总量10亿, 5钱包分配 + 通胀控制

代币分配 (总量 1,000,000,000 GNX):
  - validator   35% (3.5亿) — 验证者节点, stake 2.5亿
  - treasury    20% (2.0亿) — 平台运营/Gas Relayer补贴池
  - ecosystem   20% (2.0亿) — 生态发展/DApp激励
  - team        15% (1.5亿) — 团队&早期投资者
  - community   10% (1.0亿) — 社区治理/DAO储备

通胀参数:
  - 初始通胀率: 5%
  - 范围: 2%-7%
  - 目标staking比例: 50%
