Closes #811

Summary

  • Add array-API-compatible implementations for pad(..., mode="edge") and pad(..., mode="wrap").
  • Keep the implementation backend-agnostic and preserve the existing constant-mode behavior.
  • Extend delegated backend handling and add NumPy-oracle coverage for multidimensional, asymmetric, zero-width, singleton, and large padding cases.

Validation

  • Test suite: 70 passed, 84 skipped for unavailable optional backends
  • NumPy oracle comparisons passed
  • Ruff passed
  • mypy passed
