i18n slice 1 (A.2-A.4, A.6): narrowed English mask, marker coverage test, English retrieval stems, parse timing

Five v0.247.0 fixtures re-captured from UNCONVERTED v0.246.0 (89dd3e94) because their
one-word Hungarian data values had to become multi-word; two new cases (backups_tier_due,
app_info_installable) captured the same way — the coverage test found both gaps.
