feat: Pika Quality

[Z-G-H1]

https://github.com/OpenAtomFoundation/pikiwidb/pull/3043 https://github.com/OpenAtomFoundation/pikiwidb/pull/3047 这两处修复都涉及到了参数cache-value-item-max-size 和 max-key-size-in-cache 添加测试点： ● 验证配置项的存在性：通过ConfigGet命令确认cache-value-item-max-size 和max-key-size-in-cache 配置项存在 ● 验证配置可以被设置：通过ConfigSet命令尝试设置配置值 https://github.com/OpenAtomFoundation/pikiwidb/pull/3048 用例验证配置项 admin-cmd-list 中是否包含 "auth" 命令，确保配置被正确设置。 https://github.com/OpenAtomFoundation/pikiwidb/issues/3095 测试了两种情况： ● 使用原始 TCP 连接来模拟 telnet 客户端行为 ● 验证服务器不会崩溃并能继续处理正常命令

测试结果如下：

Summary by CodeRabbit

• Tests

  • Enhanced network stability testing with Telnet interactions, empty/multiline command handling, and response assertions.
  • Added tests for cache configuration updates and verification of retrieved values.
  • Added tests validating admin command loading and execution behavior.

• Chores

  • CI cleanup steps refined to target workspace build artifacts and specific libraries; minor Docker build label formatting adjusted.

Walkthrough

Adds a new integration test exercising Telnet/TCP interactions and extends server tests to validate cache-size configuration and admin-command loading/execution; also updates CI cleanup steps in the GitHub Actions workflow. Admin-command checks are duplicated in the server tests.

Changes

Cohort / File(s)	Summary
Network Stability Tests tests/integration/network_stability_test.go	New integration test using Ginkgo/Gomega to open TCP (Telnet) connections, send empty and multiline commands, assert server responses (e.g., "+PONG", "$4\r\nTEST"), check I/O errors, and ensure connection cleanup.
Server Configuration & Admin Tests tests/integration/server_test.go	Adds tests to get/set cache configuration values (cache-value-item-max-size, max-key-size-in-cache) and to verify admin command list loading and execution behavior; admin-cmd tests are duplicated in-file.
CI Workflow Cleanup .github/workflows/pika.yml	Replaces broad "Extreme Disk Cleanup" with targeted workspace cleanup commands removing specific build artifacts and paths, narrows deletions to the CI workspace, and minor formatting tweak to Docker labels.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Review test logic for flaky network timing and proper resource cleanup (defer closes).
• Verify duplicated admin-command assertions in server_test.go are intentional or should be consolidated.
• Confirm CI cleanup paths are safe and do not remove required artifacts (check excluded patterns).

Poem

🐰 I hopped a telnet trail so fleet,

Sent pings and blank lines—no small feat,
Cache crumbs counted, admin buttons pressed,
CI shed its excess, trimmed to best.
🥕 Tests pass, I burrow home, well-dressed.
