Qwen3-Coder-Next lands 54GB APEX quant

This is more useful than flashy: the underlying Qwen3-Coder-Next model is already the important part, and this release makes it materially easier to run without throwing away code quality.

• –The code-specific imatrix is the real value add here; calibration on code samples should preserve the weights that matter for syntax, refactors, and tool use better than generic quantization.
• –54.1GB puts it in the practical zone for serious local inference on 128GB-class machines and some multi-GPU setups, which is where large coding models start to become usable.
• –The repo's own speed claims are attractive, but real throughput will still hinge on backend, offload, and context length.
• –This is an open-source packaging win, not a new base-model launch, so the significance is in accessibility and deployment rather than benchmark novelty.
