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

[ChrisRackauckas-Claude]

Summary

Converts the root test workflow (Tests.yml) to the canonical grouped-tests.yml@v1 thin caller, with the group × version matrix declared once in test/test_groups.toml.

• .github/workflows/Tests.yml: replaces the hand-maintained group × version matrix job with a thin caller to SciML/.github/.github/workflows/grouped-tests.yml@v1. on: and concurrency: are preserved verbatim. All reusable-workflow inputs use defaults (GROUP env, check-bounds, coverage), so no with: block is needed. Linux-only (no os field).
• test/test_groups.toml (new, repo root): [Core] on ["lts","1","pre"]; [QA] on ["lts","1"].
• Category B refactor (inline Aqua/JET → QA group):
  • Aqua previously ran inline inside the Core group (@safetestset "Quality Assurance" include("qa.jl")).
  • JET previously ran as a separate nopre group with its own test/nopre/Project.toml.
  • Both are now consolidated into a QA group gated on GROUP=="QA", isolated in test/qa/Project.toml (deps = Aqua + JET + LinearAlgebra + Test + the package via [sources] path = "../..", [compat] julia = "1.10") plus test/qa/qa.jl.
  • runtests.jl, for GROUP=="QA", activates test/qa, develops the root package, instantiates, then includes qa.jl. Functional tests (Constructors / Multiplication / Division / Interface) stay under Core (and All).
  • Removed old test/qa.jl and test/nopre/; dropped Aqua from the root test/Project.toml (now isolated in test/qa).

Matrix match

Old matrix in Tests.yml:

• version = [1, lts, pre], group = [Core, nopre], with exclude (pre, nopre)
• ⇒ {(Core,1), (Core,lts), (Core,pre), (nopre,1), (nopre,lts)}

New matrix emitted by compute_affected_sublibraries.jl --root-matrix from test/test_groups.toml:

• {(Core,lts), (Core,1), (Core,pre), (QA,lts), (QA,1)}

The nopre (JET) group becomes QA with identical version coverage (lts, 1); QA additionally absorbs the Aqua check that was previously inline in Core. Same number of jobs, same version coverage, all on ubuntu-latest. Verified statically by running the matrix-computation script against this branch; TOML and YAML parse confirmed.

Notes

• The QA group is newly wired as a first-class CI group; Aqua/JET run in CI here — any failures will be triaged in a follow-up. No checks were skipped, silenced, or excluded.

Ignore until reviewed by @ChrisRackauckas.
