IPv6 listener now requires explicit --listen6 flag (disabled by default).
TCP over IPv6 works fully. UDP over IPv6 has macOS kernel limitations
(ENOBUFS on send_to). On Linux, IPv6 UDP works fine.

Usage:
  btest -s                    # IPv4 only (default)
  btest -s --listen6          # IPv4 + IPv6 on ::
  btest -s --listen6 ::1      # IPv4 + IPv6 on specific address

## Known Limitations
- **IPv6 support is experimental** (`--listen6`). TCP over IPv6 works fully. UDP over IPv6 has issues on macOS due to kernel ENOBUFS limitations with `send_to()`. On Linux, IPv6 UDP works fine. IPv6 is disabled by default.
- **Multi-connection UDP** is supported. MikroTik's multi-connection mode sends from multiple source ports which are all accepted by the server.
## Testing
