This removes the extra nftables rules that were needed for SYN/ACK capture and should be more efficient. On Windows, WinDivert is now opened as separate recv/send/sniff handles, and the sniff thread is only spawned when `--fake-autottl` is actually enabled. +Performance improvement due to packet sniffing backend changes. -Other changes: Windows exits immediately on Ctrl-C instead of waiting for cleanup, logging defers `local_time()` until the log level check passes, and `infer_hops` now correctly uses 128 (was 126).
