v0.8.0 — GLM/Qwen3 MoE decode + exo integration

What's new

• GLM-4.7-Flash decode +8% — 46 MoE layers fused via gather_qmm_swiglu custom primitive
• Qwen3-30B-A3B decode +6% — same fused MoE path
• exo integration — one-command setup (bash setup_zmlx.sh) for running ZMLX-accelerated models in exo clusters. See docs/EXO.md.
• mlx-lm compatibility layer — handles API differences across mlx-lm versions
• Auto-skip safety — models auto-skip on stock MLX when custom primitive is unavailable (0% change, no regressions)

Requirements

• Stock MLX: LFM2 gains work out of the box
• GLM/Qwen3 gains: requires building the custom gather_qmm_swiglu primitive (see docs/EXPERIMENTAL_MLX.md)
