Fix branch test coverage in classes with 0% coverage and restore branch expected coverage back to 95%

The pre-commit hook was failing because it expected 95% branch coverage, but certain classes (GetCollection and GetCollectionFacets) were showing 0% branch coverage, even though we have test cases that should cover these branches.

To temporarily resolve this issue, we lowered the required branch coverage to 90% for the pre-commit hook to pass. However, we need to investigate the cause of this discrepancy, fix the issue, and restore the required branch coverage back to 95%

从 pre-commit hook 的分支覆盖率配置开始，检查 GetCollection 和 GetCollectionFacets 类及其现有测试用例。复现报告的 0% 分支覆盖率，确定这些分支未被计数的原因，并验证在将所需分支覆盖率恢复到 95% 后 hook 能够通过。
