[CI] Add unittest Claude skill and supplement unit test coverage

[EmmonsCurse]

Motivation

To improve unit test development efficiency and standardization, a dedicated Claude skill for FastDeploy unittest generation is introduced. In addition, related unit tests need to be supplemented to improve test coverage and validation completeness.

Modifications

• Added unittest Claude skill documentation and related configurations.
• Supplemented missing unit test cases.
• Improved unit test coverage and development workflow consistency.

📋 Review 摘要

PR 概述：新增 FastDeploy unittest Claude Skill 文档，删除非规范测试脚本，补充约 39 个单测文件以提升覆盖率，同时扩展 .coveragerc omit 规则。
变更范围：.claude/skills/（Skill 文档）、scripts/.coveragerc、tests/（大量新增单测）、fastdeploy/entrypoints/openai/（删除遗留脚本）
影响面 Tag：[CI]

问题

级别	文件	概述
🟡 建议	—	PR 变更量较大（43 文件），建议拆分以降低审查难度和合入风险
❓ 疑问	tests/entrypoints/test_api_server.py	test_launch_uvicorn_exception_handled 无任何 assert，仅靠"不抛异常"通过
❓ 疑问	tests/layers/test_fused_moe_marlin_backend.py	test_create_weights_scale_shapes 中 up_gate 与 down 两个 scale shape 断言值完全相同 [4, 1, 2048]，需确认源码意图

⚠️ 本 PR 变更量较大（43 文件），建议拆分以降低审查难度和合入风险。

建议拆分方案：

• PR 1: [CI] Skill 文档 + coveragerc — .claude/skills/write-fastdeploy-unittest/, scripts/.coveragerc
• PR 2: [CI] cache_manager / layers / quantization 单测 — tests/cache_manager/, tests/layers/, tests/quantization/
• PR 3: [CI] worker / model_executor / scheduler / multimodal 单测 — tests/worker/, tests/model_executor/, tests/scheduler/, tests/multimodal/
• PR 4: [CI] entrypoints / input / inter_communicator / rl 单测 + 遗留脚本清理 — tests/entrypoints/, tests/input/, tests/inter_communicator/, tests/rl/, fastdeploy/entrypoints/openai/test_openai.py

📝 PR 规范检查

PR 结构合规，## Motivation、## Modifications、## Usage or Command、## Accuracy Tests、## Checklist 各段均存在且内容完整，标题 Tag [CI] 与 diff 主要影响面（Skill 文档 + CI 脚本 + 单测覆盖）匹配。

总体评价

整体质量较高：Skill 文档结构完整、规范清晰；抽样的 5 个测试文件（test_ipc_cache_transfer、test_fused_moe_marlin_backend、test_w8a8、test_worker_tbo、test_api_server）均有实质性断言，mock 隔离合理，命名符合规范，资源清理到位。存在一处空断言测试（test_launch_uvicorn_exception_handled）和一处 scale shape 断言待确认，建议作者核实后酌情补强，不阻塞合入。
