Mateusz Pusz 805bb969d2 feat(representation): add embed/project conversions between 2D and 3D cartesian types ...

`embed` is the canonical inclusion of the plane into space and `project` the
canonical projection back, for both vectors and tensors:
- vector: embed (x,y) -> (x,y,0); project (x,y,z) -> (x,y)
- tensor: embed the 2x2 into the top-left block of a zeroed 3x3; project keeps
  that top-left 2x2 block

They are explicit named free functions (no implicit cross-dimension conversion),
each defined for a single source dimension (embed: 2D only; project: 3D only).
The zero fill is the additive identity derived from a component (`x - x`), so no
value-initialization of the element type is required.

Also route `tensor_product` through `cartesian_tensor_from` instead of a
default-constructed result, matching the other constructing operations (the
element type need not be default-constructible).
