BeeLlama.cpp: advanced DFlash & TurboQuant with support of reasoning and vision. Qwen 3.6 27B Q5 with 200k context on 3090, 2-3x faster than baseline (peak 135 tps!)

TL;DR New llama.cpp fork! I wanted a Windows-friendly inference to run Qwen 3.6 27B Q5 on a single RTX 3090 with speculative decoding, high context without excess quantization, and vision enabled. No option did this out of the box for me without VRAM and/or tooling issues (this was before MTP PR for llama.cpp surfaced there). So I pulled out an old trick: stay up to 4 a.m. one too many times to do month+ work in a week or two. I probably lost a decent amount of hair while trying to make this all work, but now I have what seems to be a proper solution and don't mind to share.
