fix(cnnl): 修复编译器字段名并添加新字段支持，实现 cnnl-service HTTP 服务

修复内容：
1. ast.rs: 恢复原始字段名 ty: Type（而非 type_: TypeAnnotation）
   - 添加 name/version/description 字段到 Clause
   - 添加 description 字段到 Obligation
   - 添加 tests 字段到 Program
   - 添加 Expression::Raw 变体
   - 添加 ObligationFrequency::Display 实现
   - 添加 Literal::Display 实现

2. parser/mod.rs: 完全重写，基于原始版本添加新字段支持
   - 支持 name:/version:/description: 字段解析
   - 支持 test "..." { assert ... } 测试块解析
   - 支持 obligation { description: ... } 字段

3. 修复所有模块的编译错误：
   - codegen/bytecode_generator.rs
   - semantic/type_checker.rs
   - semantic/scope_resolver.rs
   - semantic/obligation_validator.rs
   - verification/constraint_generator.rs

4. 新增 cnnl-service HTTP 服务：
   - POST /api/v1/compile  - 编译 CNNL 源代码
   - POST /api/v1/parse    - 解析 CNNL 源代码（返回 AST）
   - POST /api/v1/validate - 验证 CNNL 语法
   - GET  /api/v1/health   - 健康检查
   - GET  /api/v1/version  - 版本信息
   - 监听端口 8765，已部署为 systemd 服务

测试结果：26/26 通过
