Adding a cuTile Kernel to TileGym

End-to-end workflow for adding a new operator (e.g., my_op) with cuTile backend.

Execution Rules

MUST follow these rules strictly:

1. Use TodoWrite to create the checklist below BEFORE writing any code
2. Execute steps in order — do NOT skip ahead or combine steps
3. Mark each todo as completed after finishing, in_progress when starting
4. If a step is not applicable (e.g., no cuTile impl), mark it completed with a note, do NOT silently skip
5. Each step MUST result in a file write or explicit skip decision — no silent omissions

Instructions

MUST copy this checklist to TodoWrite at the start:
