- TMDO_Cache_Layer::prefetch() / warm_post() (and so on_save_post /
on_loop_start) queried wp_wpdo_cold_{post_type} whenever cold fields
were registered, even with the cold module idle and the table never
created: every HivePress / WC save logged "table doesn't exist" errors.
They now return unless the module is write-active and the table exists.
- CacheLayerTest activates the module in setUp; new cases assert zero cold
queries while idle or when the table is missing.
- Verify: CacheLayerTest 12 OK; unit 671 OK, integration 480 OK,
phpcs (phpcs.xml) 0, stan OK; dev36 live: seeding listings/products/
vendors with cold_hp_listing idle → 0 wpdo_cold errors (was hundreds)
