Cjs interop export names local clash, fix #8950

Editor assessment

`fix: cjs interop export names local clash, fix #8950 (#8953)` names the collision class — interop helper names clashing with local exports — which is the essential fact; the inline issue reference crowds the subject, a cosmetic flaw beside the trailing PR number. No scope marks the build area. No body explains the collision's effect, but the subject identifies the failure mode precisely for a fix of this size. The noun-phrase form is acceptable given the naming. Minor ticket-placement noise and scope absence; otherwise clear and publishable.
