/**
 * Running Task Card Display E2E Test
 *
 * Tests that task cards with a running state display the correct UI controls.
 *
 * This test verifies that:
 * 1. A feature in the in_progress column with status 'in_progress' shows Logs/Stop controls (not Make)
 * 2. A feature with status 'backlog' that is tracked as running (stale status race condition)
 *    shows Logs/Stop controls instead of the Make button when placed in in_progress column
 * 3. The Make button only appears for genuinely idle backlog/interrupted/ready features
 * 4. Features in backlog that are NOT running show the correct Edit/Make buttons
