232fcf043e 📝 docs: add GPU-only density alignment test results
Document test results verifying XAttention density calculation in
GPU-only mode matches independent xattn_estimate calls.

Test results (Llama-3.1-8B-Instruct, threshold=0.9):
- 4k:  Layer 0 density 63.8%, verified 
- 8k:  Layer 0 density 65.0%, verified 
- 16k: Layer 0 density 61.6%, verified 
- 32k: Layer 0 density 50.2%, verified 
- 64k: Layer 0 density 37.0%, verified 

All tests show exact match (attn_sums diff=0, mask exact match).
