The test uses u0=nothing which triggers oneunit(Type{Any}) call that
fails on Julia 1.10 LTS. This is a known limitation of the null u0
feature on older Julia versions. Skip the test on Julia < 1.11 per
CI Health protocol Option B2 (version-conditional skip).

Note on Downgrade Tests
The Downgrade and Downgrade Sublibraries workflows have been failing since they were added (July 2025). This is a separate issue related to dependency resolution at minimum compat bounds causing
OrdinaryDiffEqNonlinearSolveto fail to precompile. A separate issue should be created to investigate this.Test plan
