Prep for v1.51.1

[odow]

Basic

• version field of Project.toml has been updated
  - If a breaking change, increment the MAJOR field and reset others to 0
  - If adding new features, increment the MINOR field and reset PATCH to 0
  - If adding bug fixes or documentation changes, increment the PATCH field

Documentation

• Add a new entry to docs/src/changelog.md, following existing style

Tests

• https://github.com/jump-dev/MathOptInterface.jl/actions/runs/26428199400
• If new tests were added, ensure that MOI.Test.version_added is implemented.

We should first tag v1.51.1 without #3001, so that people see with the new tests that they don't implement bridge cost correctly, and then we add #3001 in v1.52

I regarded them both as a bug-fix. What's the problem with just making a single release? The only relevant failure is DiffOpt.

[blegat]

We might have failures in other packages that we don't test. Even if they are bug-fixes, that will break existing code.

[blegat]

So if you are developing an MOI layer and you use MOI.Test.runtests, you'll see that you have a bug when we release v1.15.1, then you have a head-start to fix it before we make the next release. The next release can be v1.15.2, it doesn't matter, we just need to give people a head-start

[odow]

But wouldn’t the releases be a day apart anyway? There’s not much point in delaying. And it only really affects complicated layers, which most people are not writing.

[blegat]

We can wait a few days between v1.15.1 and v1.15.2. But if you're fine with it, we can also just release this, let's just first release new version of the four packages that we had to update (EDIT: done).

[blegat]

DiffOpt is fixed now that we released POI

I'm going to merge and tag this as-is.

JuliaFormatter changed: JuliaEditorSupport/JuliaFormatter.jl#1002

This is probably going to cause a lot of pain across jump-dev. I'll wait to see if it was intentional. If so, I'll make a separate PR updating the formatting. Before then I'll pin the version.

[odow]

Okay. I'm going to merge. I'll deal with the consequences.
