Canonical CI: grouped-tests.yml + root test/test_groups.toml

[ChrisRackauckas-Claude]

Summary

Converts the root test workflow (.github/workflows/Tests.yml, name: CI) to the canonical SciML grouped-tests.yml@v1 thin caller, with the group x version matrix declared once in a root test/test_groups.toml.

• .github/workflows/Tests.yml — the matrix test job (which previously hand-maintained group: {CPU, QA} x version: {lts, 1} and called the legacy per-job tests.yml@v1) is replaced by a thin caller to SciML/.github/.github/workflows/grouped-tests.yml@v1 with secrets: inherit. on: and concurrency: are preserved verbatim; filename and name: kept. No with: overrides needed (root reads GROUP, coverage/check-bounds/coverage-directories all at defaults, no apt packages).
• test/test_groups.toml (new, repo root) — [Core] and [QA], each on ["lts", "1"]. Linux-only (no os axis).
• test/qa/Project.toml (new) — isolated QA environment containing only the QA tooling (Aqua, ExplicitImports, Documenter) plus the deps the QA checks reference (SciMLSensitivity, Lux, Random, OrdinaryDiffEq, NonlinearSolve, Test), with DeepEquilibriumNetworks brought in via [sources] path = "../.." and julia = "1.10". This keeps the heavy QA tooling out of the main test env and out of reverse-dependency resolution.
• test/qa/qa.jl — the QA checks (Aqua, ExplicitImports, Doctests), moved verbatim from the old test/qa_tests.jl.
• test/runtests.jl — GROUP == "QA" now Pkg.activates test/qa, Pkg.develops the package, Pkg.instantiates, then includes qa/qa.jl. Functional tests run under canonical GROUP Core (CPU/ALL still accepted for back-compat).
• test/shared_testsetup.jl — BACKEND_GROUP == "core" now selects the CPU device, so the renamed Core group behaves exactly as the old CPU group did.

Matrix match

Old caller matrix	New (test_groups.toml -> grouped-tests.yml)
(CPU, lts)	(Core, lts)
(CPU, 1)	(Core, 1)
(QA, lts)	(QA, lts)
(QA, 1)	(QA, 1)

Same 4 cells: the functional CPU group is renamed to the canonical Core (QA unchanged), version set {lts, 1} preserved, Linux-only ubuntu-latest, no OS axis. Verified statically by running scripts/compute_affected_sublibraries.jl <root> --root-matrix from SciML/.github@v1, which emits exactly {(Core, lts), (Core, 1), (QA, lts), (QA, 1)}.

Project.toml already satisfies the benign-metadata checks ([compat] julia = "1.10" LTS floor; every [extras] dep has a [compat] entry), so no metadata changes were needed.

Notes

The QA group's Aqua/JET-style checks run in CI under this wiring (Aqua, ExplicitImports, Doctests). No checks were skipped, silenced, or excluded; any QA failures surfaced in CI will be triaged in a follow-up.

This was a structural conversion only — tests/Aqua/JET were not run locally; the QA group runs in CI.

Ignore until reviewed by @ChrisRackauckas.

Pushed 8575f2d: folded the bespoke .github/workflows/GPU.yml into the canonical group matrix.

• test/test_groups.toml gains [GPU] — versions = ["1"], runner = ["self-hosted", "Linux", "X64", "gpu"], timeout = 240 (the old workflow's exact runs-on labels and timeout-minutes).
• test/runtests.jl: GROUP == "GPU" sets ENV["BACKEND_GROUP"] = "CUDA" and runs the same Utils/Layers suite — exactly what the old workflow's julia-runtest step with BACKEND_GROUP: CUDA did (shared_testsetup.jl reads BACKEND_GROUP to select the CUDA mode).
• GPU.yml deleted. Its second job (gpu-docs) was a duplicate docs build/deploy: the centralized documentation.yml (SciML/.github documentation.yml@v1) is already on main and remains the docs pipeline.

Static verification: TOML parses, Meta.parseall on runtests.jl clean, and the v1 compute_affected_sublibraries.jl --root-matrix emits the GPU cell:

{"group":"GPU","version":"1","runner":["self-hosted","Linux","X64","gpu"],"timeout":240,"num_threads":1,"continue_on_error":false}

Added the SciMLTesting v1.2 folder-based run_tests harness on top of this grouped-tests conversion; merges as one PR (grouped-tests + SciMLTesting v1.2).
