QA: Aqua/JET findings marked @test_broken pending fix

[ChrisRackauckas-Claude]

The grouped-tests QA group (GROUP=QA) has one genuine Aqua finding that is currently marked @test_broken so CI is green. It should be fixed and un-broken.

Finding:

• Aqua.test_deps_compat (extras check): the test-only extra Pkg (declared in [extras] and [targets].test) has no [compat] entry. Aqua flags this:

  Static does not declare a compat entry for the following extras: Pkg
  

Current state (test/qa/qa.jl): Aqua.test_deps_compat(Static, check_extras = false) keeps the deps/weakdeps compat checks live, and the extras failure is recorded as @test_broken false. The deps and weakdeps sub-checks still pass normally.

Fix: add a [compat] entry for Pkg (e.g. Pkg = "1") in the root Project.toml, then restore Aqua.test_deps_compat(Static) and remove the @test_broken.

Note: Aqua.test_piracies(Static, broken = true) (1 instance) is a separate, pre-existing broken marker not introduced here.

Ignore until reviewed by @ChrisRackauckas.

Fixed properly in #176: added Pkg = "1" to [compat] in Project.toml and restored the full Aqua.test_deps_compat(Static) call (dropped check_extras = false, removed the @test_broken false sentinel). The separate, pre-existing Aqua.test_piracies(Static, broken = true) marker is left untouched. Verified locally with GROUP=QA on Julia 1.11: Aqua testset passes (9 pass / 1 broken = the pre-existing piracy marker / 10 total), ExplicitImports 2/2.

This issue's actionable item was only the Pkg deps_compat nit (the piracy marker is explicitly noted as pre-existing/not tracked here), so closing. Ignore until reviewed by @ChrisRackauckas.
