Improve `mise test:init`

[2chanhaeng]

Summary

Improve mise test:init with optimization.

Problem

Currently, running mise test:init without any constraints tests a total of 560 cases. Even on Apple's latest M5 chip, it takes over 2 hours. Optimization is desperately needed.

Proposed Solution

Considering the following approaches:

• Concurrent test execution
• Memory leak detection and prevention
• Caching used packages
• Add --unify-mq-kv: Test cases where KV and MQ have the same options. If an option is unavailable on the other side, fallback to in-process or in-memory.
• etc.
