Subject: [PATCH] fix: bump sing-tun for nftables max-address interval EEXIST

route_exclude_address ranges that reach 255.255.255.255 / ffff:...:ffff
made nftablesCreateIPSet encode a duplicate interval start/end key.
Point sing-tun at the fix that omits the exclusive end when Next()
overflows (H-TTTTT/sing-tun@8775818, SagerNet/sing-tun#83).

Fixes #4316
