 * PR Vision -- full data teardown on uninstall.

 * Drops the custom prv_ai_visibility table and deletes every wp_options
 * row whose name starts with "prv_". WP-Cron events are already cleared
 * by PRV_Deactivator on deactivation; this runs after that.
 *
 * v0.2.0 additions: prv_models_schema_version, prv_config_versions,
 * prv_active_config_version, prv_api_key_status, prv_api_key_last_check,
 * prv_last_run_at, prv_last_run_counts, prv_last_run_truncated,
 * prv_last_run_truncated_at -- all purged by the prv_ wildcard DELETE below.
 *
 * v0.2.3 addition: prv_provider_key_enc (encrypted API key) -- also purged
 * by the prv_ wildcard DELETE below. No plaintext is stored.
 *
 * @see ARCHITECTURE.md          -- Section Uninstall specification.
 * @see class-prv-deactivator.php -- Clears cron on deactivation.
 * @see class-prv-key-store.php   -- Encrypted key storage (prv_provider_key_enc).
