Fix downgraded sublibrary compat bounds

[ChrisRackauckas-Claude]

Summary

This draft PR fixes the current Downgrade Sublibraries failures for the shared OptimizationBase/SparseConnectivityTracer lower-bound path and the SimpleOptimization lower-bound path.

Ignore this PR until reviewed by @ChrisRackauckas.

Changes:

• Raise OptimizationBase lower bounds for ADTypes and SparseConnectivityTracer to versions compatible with the current dependency stack.
• Add test-only LogExpFunctions compat to affected sublibraries so downgraded test manifests choose the 0.3.28 - 0.3 range required by SparseConnectivityTracer 1.x.
• Update SimpleOptimization lower bounds and pass Val(false) for Broyden linesearch, matching SimpleNonlinearSolve 2.x constructors.

Local verification

All commands used timeout 3600, Julia 1.10, a local depot, and Pkg.test(...; allow_reresolve=false) after local downgrade-manifest generation.

Passed:

• lib/OptimizationBBO: Core | Pass 25 Total 25
• lib/OptimizationEvolutionary: Core | Pass 32 Total 32
• lib/OptimizationNOMAD: Core | Pass 4 Total 4
• lib/OptimizationSciPy: Core | Pass 160 Broken 1 Total 161
• lib/SimpleOptimization: Core | Pass 7 Total 7
• Runic --check lib/SimpleOptimization/src/SimpleOptimization.jl
• git diff --cached --check

Remaining separate failures observed and intentionally not fixed here:

• lib/OptimizationNLPModels: after downgrade resolution, Pkg.test(... allow_reresolve=false) still hits a SciML stack manifest conflict involving DiffEqBase, SciMLBase, ModelingToolkitBase, FastBroadcast, and RecursiveArrayTools.
• lib/OptimizationQuadDIRECT: downgrade generation does not add URL [sources] package QuadDIRECT to the generated manifest, so Pkg.test errors that QuadDIRECT is a direct dependency missing from the manifest.
