[Copilot]

Pull request overview

Accepts the baseline changes for JS declaration emit behavior in nodeModulesAllowJsExportAssignment across Node16/18/20/nodenext module modes, as discussed in #3552, by moving these diffs from triaged to accepted.

Changes:

• Remove the #3552 entry and associated diffs from testdata/submoduleTriaged.txt.
• Add an accepted note + accept-list entries for the same diffs in testdata/submoduleAccepted.txt.
• Add reference accepted baseline .js.diff files capturing the new declaration emit output (export assignment ordering and preserving side-effect imports).
