【Hackathon 9th No.82】add test_prefix_cache

[Echo-Nie]

Objective

• Hit rate calculation
• Cache eviction
• GPU ↔ CPU fallback/swap

Result

• Task 1 (first request): Required 2 blocks, fully allocated on GPU. Hit Rate = 0.00 → expected for first allocation.
• Task 2 (exceeds GPU capacity): Required 3 blocks: 2 blocks hit on GPU, 1 block allocated on CPU (fallback). Hit Rate = 0.67 → confirms GPU+CPU cooperative allocation works.
• Task 1 (second request): Previously allocated GPU blocks were fully hit. Hit Rate = 1.00 → confirms cache reuse works as expected.

OK

There are still some bugs being fixed at the moment, so a review is not needed for now.

I misunderstood the meaning, so this is an invalid PR and it is closed.
