…u-kernels` skill.

This PR extends the XPU kernel optimization skill with a new pattern for pruning Triton autotune configurations that are likely to spill registers on Intel XPU. The existing Xe-Forge workflow already detects register spills through profiling and recommends GRF/liveness mitigations; this change adds a proactive pruning strategy that can reduce wasted compile and benchmark time for obviously spill-prone configs.
