Adds a full implementation of `tensordot` for n-dimensional arrays, supporting both numeric and paired axis specifications via the new `AxisSpec` enum. The design mirrors NumPy’s `tensordot` behaviour while integrating cleanly with ndarray’s trait-based approach for the ``dot`` product and existing shape and stride logic. All internal reshaping and permutation operations use `unwrap` and `expect` with explicit safety reasoning: each call is guarded by dimension and axis validation, ensuring panics can only occur under invalid `AxisSpec` input. Documentation and inline comments describe these invariants and the exact failure conditions. Includes tests verifying correct contraction for both paired and integer axis modes.
