Bump MSRV to 1.87 and nalgebra to the 0.34 release (#16045)

* Bump MSRV to 1.87 and nalgebra to the 0.34 release

This commit updates nalgebra to the latest release 0.34 and also
increases our MSRV to the minimum version compatible with that nalgebra
release 1.87. Nalgebra 0.34 was release in July of 2025 and we didn't
upgrade at the time because we had just increased our msrv to 1.85 and
bumping it again would have been overly onerous. But since we're now
using nalgebra more in critical code paths (2q decomposition) it makes
sense to make this change now especially since rust 1.87 is over 1 year
old now (being release in March 2025).

The rust code changes made in this are to fix clippy warnings due to new
clippy rules being enabled with the higher msrv of 1.87.

* Update releasenotes/notes/msrv-187-fe3d9818f5c4103d.yaml
