test: enhance test coverage configuration and add comprehensive merge utility tests

Updated coverage configuration to enforce 95% branch and line coverage requirements across all modules, moved exclusion patterns to pyproject.toml, and added extensive test cases for merge utility functions including tuple, set, frozenset, and object merging with no_new_field parameter.

将覆盖率配置更新为在所有模块中强制执行 95% 的分支和行覆盖率要求，将排除模式移至 pyproject.toml，并为合并实用程序函数添加了广泛的测试用例，包括 tuple、set、frozenset 和对象合并以及 no_new_field 参数。
