test: 增强快照测试基础设施，添加安全验证和覆盖率改进

- 在 EnumExtensionsGeneratorSnapshotTests.cs 中补充 snapshotFileNameSelector 的 null 分支覆盖，新增默认快照文件名选择器用例及对应快照资产

- 强化 GeneratorSnapshotTest.cs 的快照路径校验，拒绝空白文件名、绝对路径和目录遍历攻击；将辅助器改为通过 Roslyn GeneratorDriver 读取真实生成结果并验证编译，消除仅依赖 TestState.GeneratedSources 导致的空跑风险

- 新增 GeneratorSnapshotTestSecurityTests.cs 安全回归测试，覆盖绝对路径拒绝和目录逃逸防护两个分支

- 将 Priority、Logger、ContextAware 三组生成器测试统一指向仓库内快照目录，并补齐缺失的快照资产以支持现在强制执行的生成验证
