🧹 Remove unused interactWithUrwis function

[marcin2121]

🎯 What: Removed the unused interactWithUrwis function and its parent file app/actions/urwis-pet.ts.
💡 Why: The file app/actions/urwis-pet.ts contained only a single function, interactWithUrwis, which was exported but never imported or utilized anywhere else in the application. An active version of interactWithUrwis actually exists and is used from app/actions/tamagotchi.ts. Removing this dead code prevents confusion and improves the overall maintainability of the codebase by eliminating unnecessary files.
✅ Verification: Verified that the function was unused by grepping the codebase. Verified file deletion. Successfully ran npm run lint and npm run build after the file was removed, confirming that no regressions were introduced.
✨ Result: Cleaned up the codebase by removing dead, unused code, leading to improved code health.
