Composing PQ transport with ZAP RPC was already a 2-line pattern:
raw, _ := zwing.Dial(ctx, addr, cfg)
conn := zap.NewConn(raw, nil)
Two lines means two ways to mess it up (forget to wrap, leak the
raw conn). Add the canonical one-call wrappers so there is exactly
one way to do it:
conn, _ := zwing.DialZAP(ctx, addr, cfg)
ln, _ := zwing.ListenZAP(":9999", cfg)
srv := zap.NewServer(ln, handler)
Pairs with luxfi/api v1.0.10 zap.NewListener. No new wire format,
no new dep — these are sugar over the existing primitives.
