When an export policy change causes a previously advertised path to be filtered, soft reset out must send an explicit withdrawal, otherwise the neighbor can keep using stale routes. Track advertised paths for all peers so that soft reset can distinguish routes that were actually sent from routes that were already filtered. For VRF peers, normalize filtered VPN candidates to the local unicast form before checking advertised state, matching the path key used when the route was originally sent. Add regression coverage for regular, add-path, and VRF soft-reset withdrawals.
