The `multisession_*` variants and `non_exclusive_heartbeat_interval_ms` remain in place.\n\n**Why**\n\nThis removes now-unused, single-session polling config in favor of the multisession polling settings that replaced it; it is cleanup of dead config surface rather than a change to visible behavior.\n\n- Area: Elsewhere\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 2\/5"}
