Allow LogExpFunctions 1.x

[ChrisRackauckas-Claude]

LogExpFunctions = \"0.3.28\" is [0.3.28, 0.4). That floor was set in #195 because loglogistic / logitexp / log1mlogistic / logit1mexp landed in LogExpFunctions 0.3.28.

LogExpFunctions 1.0.0 (2026-05-28) did not remove those functions. The 1.0 breaking note is a weaker promise on log2mexp (https://github.com/JuliaStats/LogExpFunctions.jl/releases/tag/v1.0.0). The SCT extension still imports the same names and generates the same 1-to-1 / 2-to-1 tracer overloads.

Without this, any package that depends on LogExpFunctions 1 (e.g. SciML NonlinearSolveBase) cannot share an environment with SparseConnectivityTracer.

Local Julia 1.10.11, Pkg.develop this branch + LogExpFunctions 1.0.1:

SCT 1.2.2
LEF 1.0.1
EXT SparseConnectivityTracerLogExpFunctionsExt
Jacobian Global | 25 passed
Jacobian Local  | 25 passed
Hessian Global  | 25 passed
Hessian Local   | 25 passed

All 26 names the extension imports (logistic, logit, xlogx, logaddexp, …) are still defined on 1.0.1.
