[CI] Remove deprecated IPC unit tests

[EmmonsCurse]

Motivation

The IPC-related unit tests are no longer applicable and have been deprecated. Keeping these tests in CI introduces unnecessary maintenance overhead and execution time without providing meaningful validation coverage.

Modifications

• Removed deprecated IPC-related unit tests.
• Cleaned up obsolete test coverage associated with IPC functionality.
• Reduced unnecessary CI execution workload and maintenance cost.

📋 Review 摘要

PR 概述：在 CI 覆盖率测试配置中忽略已废弃的 IPC 相关 e2e 测试
变更范围：tests/cov_pytest.ini
影响面 Tag：[CI]

问题

未发现阻塞性问题。

📝 PR 规范检查

✓ 标题格式合规（[CI] Tag 正确），描述结构完整，包含所有必填段落。

轻微备注：PR 描述中 Modifications 提到 "Removed deprecated IPC-related unit tests"，实际变更仅是在 cov_pytest.ini 中添加 --ignore 指令跳过这些测试，测试文件本身并未从仓库中删除。描述措辞可更精确为"在覆盖率测试中排除了废弃的 IPC 测试"，但不影响合入。

总体评价

变更简单且风险极低，仅在 pytest 覆盖率配置中排除两个已废弃的 IPC/splitwise 相关 e2e 测试文件。两个测试文件经确认均为 IPC 传输缓存相关的 splitwise 部署测试，排除合理。
