sleepy 6ad84d543c feat: phased patch system for Intel Arc GPU performance fixes
3-model council (GLM-5.1, Minimax-M2.7, Kimi k2p5) analyzed Intel Arc GPU
performance issues and produced patches for llama.cpp:

Phase 1 - SYCL Sync: Enable graph execution by default (GGML_SYCL_DISABLE_GRAPH)
Phase 2 - SYCL Kernel: Fix VER_GEN12/13 thresholds, tune DMMV_X/MMV_Y
Phase 3 - Vulkan Intel: Arc 140T device-ID Xe2 override

Includes:
- Phased apply script (apply-phase.sh [1|2|3|all])
- Master apply script with --status/--reverse/--dry-run
- Per-phase READMEs with testing checklists
- Council deliberation logs (gitignored in logs/)

Verified: all patches apply/reverse cleanly via git apply.
Static verification: VER_GEN arithmetic and DMMV_X divisibility pass.
