feat: 引入分层配置生命周期，支持变量引用和 JSON Schema 校验

- 新增 src/server/config/ 模块（types、issues、variables、normalizer、schema）
- 配置布局从 server.host/server.port 切换为 server.listen.host/server.listen.port
- 移除 HOST/PORT 隐式环境变量覆盖，改为 YAML 显式 ${KEY} 变量引用
- 支持 ${KEY}、${KEY|default}、${KEY|}、$${KEY} 变量语法
- 使用 @sinclair/typebox + ajv 实现运行时严格契约校验和 JSON Schema 导出
- 新增 scripts/generate-config-schema.ts 和 config.schema.json
- 新增 bun run schema / schema:check 命令，check 先执行 schema:check
- 更新 README.md 和 DEVELOPMENT.md 匹配新配置体系
- 新增变量解析、schema 校验和 schema 同步测试
