Honor approved reexports in API docs QA

[ChrisRackauckas-Claude]

Summary

Make run_qa apply approved external reexports_allow names to both public-API docstring and rendered-documentation checks. This restores the documented facade-package policy while preserving caller-provided ignores and continuing to check package-owned names even if they appear in the reexport allow-list.

Ignore this PR until reviewed by @ChrisRackauckas.

Root cause

The policy introduced in #62 initially merged approved external reexports into the API documentation ignore lists. Commit c745b75 immediately removed that routing while retaining the reexports_allow interface and its documented owner-documentation policy. run_qa therefore approved facade reexports in one check and then incorrectly required the facade to document/render those same externally owned bindings in the next check.

The fix intersects reexports_allow with the package's actual external public reexports, then merges those names into both ignore and rendered_ignore. The intersection is important: a locally owned name merely present in reexports_allow is still checked.

Failing before

The new integration test was run against the unfixed source:

$ julia +release --project=. --startup-file=no -e 'using Pkg; Pkg.test()'
run_qa public reexport integration (default on): Test Failed
run_api_docs: public API names missing a docstring
  undocumented = [:owned_function]
ERROR: Some tests did not pass: 433 passed, 1 failed, 0 errored, 0 broken.

Passing after

The repository has no Documenter build entrypoint. Its rendered public-API behavior is exercised directly by the regression suite.

An additional unfiltered self-QA probe exposed independent clean-main failures in stdlib compatibility metadata and ExplicitImports source analyzability. They are not hidden or mixed into this change and are addressed separately in #64 and #65. The remaining qualified-access audit is also being handled separately.
