format-check failing on master since #961: sublibrary test/runtests.jl not Runic-formatted

[ChrisRackauckas-Claude]

Summary

The format-check (Runic) workflow has failed on every master run since commit 7517893 ("test: uniformize monorepo onto OrdinaryDiffEq canonical structure", #961, merged 2026-06-08). Six files are flagged:

• lib/BracketingNonlinearSolve/test/runtests.jl
• lib/NonlinearSolveFirstOrder/test/runtests.jl
• lib/NonlinearSolveHomotopyContinuation/test/runtests.jl
• lib/NonlinearSolveQuasiNewton/test/runtests.jl
• lib/NonlinearSolveSpectralMethods/test/runtests.jl
• lib/SimpleNonlinearSolve/test/runtests.jl

All six fail on the same construct, the Pkg.develop([...]) call in the activate_qa_env helper that #961 added to each sublibrary's test/runtests.jl. Runic wants:

-        Pkg.develop([
-            Pkg.PackageSpec(path = joinpath(@__DIR__, "..")),
-            Pkg.PackageSpec(path = joinpath(@__DIR__, "..", "..", "NonlinearSolveBase")),
-        ])
+        Pkg.develop(
+            [
+                Pkg.PackageSpec(path = joinpath(@__DIR__, "..")),
+                Pkg.PackageSpec(path = joinpath(@__DIR__, "..", "..", "NonlinearSolveBase")),
+            ]
+        )

Evidence

• Failing on 633d93a: https://github.com/SciML/NonlinearSolve.jl/actions/runs/27316871345 (same 6 files)
• Failing on 45c88b9: https://github.com/SciML/NonlinearSolve.jl/actions/runs/27148997116 (same 6 files)
• First failing with this file set: the run on 7517893 itself, https://github.com/SciML/NonlinearSolve.jl/actions/runs/27134151806

Reproduced locally with Runic v1.7.0 on Julia 1.11: Runic.main(["--check", file]) returns 1 for all six files (and 0 for e.g. src/NonlinearSolve.jl).

Fix

Run runic -i on the six files (or on the repo) and commit. One mechanical formatting commit.
