Module tensor_like 

TensorLike trait for unifying tensor types.

This module provides a fully generic trait for tensor-like objects that expose external indices and support contraction operations.

Design

The trait is fully generic (monomorphic), meaning:

• No trait objects (dyn TensorLike)
• Uses associated type for Index
• All methods return Self instead of concrete types

For heterogeneous tensor collections, use an enum wrapper.

Structs
