refactor: 移除独立 hub/proxy/executor/gateway crate，统一为 gateway tunnel 架构

- 删除 aether-hub、aether-proxy 独立项目及其 Dockerfile/配置 - 删除 crates/aether-executor 和 crates/aether-gateway 全部模块 - 新增 apps/ 目录作为应用入口 - 将 hub 概念重构为 gateway tunnel transport - 将 executor 重构为 execution runtime - 新增 tunnel.rs 合约定义和 testkit tunnel/execution_runtime 模块 - 更新 Python 服务层和测试适配新架构命名
