- Add TMDO_Promotion_Guard: HivePress models read every meta key with an
empty-key get_*_meta() and WooCommerce does the same for products (and
writes stock/sales with direct SQL), so on those sites native meta must
stay authoritative. Promotion to aeav_only is refused in
TMDO_Mode_Manager::set() (covers REST, CLI, phases, auto-promoter) for
post/user/term/comment with HivePress and post/user with WooCommerce;
TMDO_Post_Migration::cleanup() and the cleanup phase refuse too.
Demotion stays open; filter tmdo_promotion_guard_allow overrides.
- Admin notice lists guarded entities already in aeav_only with the
restore-native command (no forced demotion on read).
- Verify: PromotionGuardTest 8 OK; unit 668 OK, integration 480 OK,
phpcs (phpcs.xml) 0, stan OK; dev36 live: 4 promotions + post-cleanup
refused, wpdo_bridge_modes unchanged
