📝 Walkthrough

Walkthrough

This PR removes tile.sel from the RequiresRowMajorLayout() allowlist in pto_ops_common.cpp. The op will no longer be auto-configured by generic N-ary op layout logic and instead continues via its dedicated registration path with explicit layout settings.

Poem

🐰 A small hop through layout land,
tile.sel takes a different strand,
No more auto-config today,
Dedicated registration finds its way! ✨
