Add proper management of parameter times quadratic terms

[joaquimg]

Closes #144

Should we remove QuadraticObjectiveCoef in this PR?
A: To do in a followup PR

Claude usage disclosure:
1 - I wrote a plan and iterated with claude on it.
2 - claude wrote a first pass.
3 - I have been cleaning up some mess for the last 2-days.

Thoughts on simplifying the documentation here: #207

We could move the PH tutorial to JuMP. I don't think POI is the right place for it. They're also not tested.

How much of this was Claude?

1 - I wrote a plan and the iterated with claude
2 - claude wrote a first pass

[joaquimg]

I am happy to move tutorials out of here

[joaquimg]

best claude use case: handle ScalarQuadraticFunction's 2 versus 1/2

[odow]

Okay. Rebase, delete the plan, and add some minimal docs. I've copy-pasted the PH tutorial; I'll add it to JuMP, and then we can switch it to POI once we tag the next release.

[joaquimg]

Remove old quadratic stuff in a follow-up PR?

[odow]

Yeah a different PR.

[odow]

I rewrote the PH tutorial jump-dev/JuMP.jl#4117.

Once we tag a new version of POI, we can change from Ipopt to HiGHS.

[odow]

I'm going to require 100% test coverage before we merge this.

Me too, I am working on it.

[joaquimg]

@odow , this should be ready
