/*!
 * Integration tests for the native trigger system (Google).
 *
 * Tests cover 4 business-logic areas:
 * 1. Resource path change — cleanup old path, recreate at new path
 * 2. Config loading — workspace-level, instance-level, token update
 * 3. Channel expiration renewal — should_renew_channel pure logic
 * 4. Delete workspace integration — full cascade, cleanup preserves triggers, parse_stop_channel_params
