QA: run_qa v1.6 form + ExplicitImports

[ChrisRackauckas-Claude]

Ignore until reviewed by @ChrisRackauckas.

Brings this repo's QA group onto the SciMLTesting v1.6 run_qa form and enables the ExplicitImports checks.

test/qa/qa.jl

Replaces the hand-rolled Aqua.test_all + JET.test_package body with:

using SciMLTesting, FastPower, JET, Test

run_qa(FastPower; explicit_imports = true)

ExplicitImports findings

FastPower's src/FastPower.jl imports nothing external (root [deps] is empty). All six EI checks pass with no curation:

check	result
no_implicit_imports	PASS
no_stale_explicit_imports	PASS
all_explicit_imports_via_owners	PASS
all_qualified_accesses_via_owners	PASS
all_qualified_accesses_are_public	PASS
all_explicit_imports_are_public	PASS

No ei_kwargs ignore-lists and no ei_broken needed.

Dropped @test_broken (closes #53)

The old qa.jl carried Aqua.test_all(FastPower; deps_compat = (; check_extras = false)) plus a @test_broken false for the deps_compat (extras) finding tracked in #53. That finding was the Pkg extra missing a [compat] entry — and Pkg was already removed from the root [extras]/test target in #54. Verified against released SciMLTesting 1.6.0 that the full default Aqua.test_all(FastPower) now passes the deps_compat (extras) sub-check, so the marker was stale. The check_extras = false tweak and the @test_broken are both dropped (a fix, not a silenced check). Issue #53 can be closed.

test/qa/Project.toml

• SciMLTesting compat "1" → "1.6".
• ExplicitImports stays transitive via SciMLTesting (not listed directly).
• Aqua kept as a direct dep (its ambiguities sub-check child-procs and needs Aqua in the env), JET and SafeTestsets kept (SafeTestsets is required by the folder-model @safetestset wrapper).

Verification (local)

Clean depot, released SciMLTesting 1.6.0 (no dev-from-branch; Pkg resolved SciMLTesting v1.6.0), GROUP=QA via the run_tests() folder-model:

Test Summary: | Pass  Total   Time
QA/qa.jl      |   18     18  28.6s

18/18 Pass, 0 Fail / 0 Error / 0 Broken. Aqua full-default test_all (8 sub-checks), JET, and all 6 EI checks confirmed individually green.
