Module texture_cache 

2D tile-based texture cache simulation.

Models the texture caching subsystem present on GPU hardware — a fixed-size cache organised in 2D tiles. Each cache line holds a rectangular tile of texels. The cache tracks:

• Hit/miss counts per request.
• LRU eviction — the least-recently-used tile is evicted when the cache is full and a new tile must be fetched.
• Prefetch hints — callers can warm the cache for anticipated accesses without incrementing the hit counter.

All structures are CPU-side simulations; no actual GPU memory is allocated.
