feat: publish the corrected platform files

export_native now writes into exports/ by default, and beside each
platform's corrected file a report naming every change, where the run
printed five per kind. A new site page lists each platform with its
original file, a download of the corrected one and every corrected,
filled or withheld value. Each platform page links to its row.
