Release v0.6.8

[lkdvos]

MatrixAlgebraKit.jl v0.6.8

Bug-fix release addressing several pullback issues — GPU compatibility for svd_pullback! and eigh pullbacks, correct handling of fully truncated decompositions, and a cotangent-mutation bug in the LQ pullback — plus a new project logo. (Shout-out to @VictorVanthilt)

Highlights

• svd_pullback! now works on the GPU (#232).
• eigh pullback now works on CUDA arrays (#235).
• Pullbacks of eig_trunc, eigh_trunc, and svd_trunc no longer error when truncation keeps no values; the zero-rank case in svd_pullback! is also handled (#233).
• LQ pullback no longer mutates the input cotangents (#226).
• New MatrixAlgebraKit logo (#230).

Should we also get the GPU fixes for eig(h)_pullback in?

I'll rebase and include them once the eig ones get fixed?

If you want to get this out asap I'd just merge it, I probably won't get to debugging the eig failure until tomorrow
