Transpose with SMatrix elements falsely seems strided

[nhz2]

Because transpose also takes the transpose of the elements, if the elements are changed by transpose the result should not be strided and strides should fail.
However, currently this is not the case.

MWE:

julia> using LinearAlgebra, StaticArrays

julia> a = [SA[1;2;;3;4]]
1-element Vector{SMatrix{2, 2, Int64, 4}}:
 [1 3; 2 4]

julia> transpose(a)
1×1 transpose(::Vector{SMatrix{2, 2, Int64, 4}}) with eltype SMatrix{2, 2, Int64, 4}:
 [1 2; 3 4]

julia> pointer(transpose(a))
Ptr{SMatrix{2, 2, Int64, 4}}(0x000078472e337f20)

julia> strides(transpose(a))
(1, 1)

julia> unsafe_load(pointer(transpose(a))) == transpose(a)[1]
false

Adjoint only defines strides on Adjoint{<:Real, <:AbstractVecOrMat}.

The fix is to only define Transpose strides on Transpose{<:Number, <:AbstractVecOrMat} since transpose on Number is identity.

Here is an example of a downstream bug caused by this, generated by Claude Code:

julia> using LinearAlgebra, StaticArrays, ChunkCodecLibZlib

julia> a = [SA[1;2;;3;4]];

julia> t = transpose(a)
1×1 transpose(::Vector{SMatrix{2, 2, Int64, 4}}) with eltype SMatrix{2, 2, Int64, 4}:
 [1 2; 3 4]

julia> bytes = reinterpret(UInt8, vec(t));

julia> enc = encode(ZlibEncodeOptions(), bytes);

julia> reinterpret(SMatrix{2,2,Int,4}, decode(ZlibDecodeOptions(), enc))
1-element reinterpret(SMatrix{2, 2, Int64, 4}, ::Vector{UInt8}):
 [1 3; 2 4]      # <-- the *parent's* contents, not t[1] = [1 2; 3 4]
