nostr: money-path split — slatepacks over the mixnet exit, everything else clearnet

The wallet routed its ENTIRE relay.floonet.dev session (own identity, recipient
lookups, profile, catch-up, subscribe, publish) through the scoped Nym exit,
saturating its metered free-tier bandwidth so a payment gift-wrap arrived
minutes late or dropped — while nostr-sdk falsely reported "sent" (it returns on
the local mixnet-stream write, not a relay OK). Root cause was contention: ~97%
of the exit's relay bytes were non-payment overhead.

Split the nostr service into two clients:
- money client (Nym scoped exit): kind-1059 slatepacks + gift-wrap
  subscribe/catch-up + recipient resolution — NIP-05 name lookup (already
  mixnet via the HTTP tunnel) and the kind-10050 DM-relay lookup (moved here;
  it's private payment-target resolution, and cheap). Relays kept, not dropped.
- general client (clearnet): own identity (0/10002/10050), discovery, the fat
  kind-0 profile/avatar, general subs, and catch-up of non-1059.

Plus confirm-before-sent: a payment publish is not reported "sent" until a real
relay OK read-back confirms it — a slow/failed exit now surfaces as a retryable
error instead of silent money loss.

Runtime-verified: a normal session puts 0 bytes on the scoped exit (all
clearnet); a kind-1059 slatepack rides the exit and lands on relay.floonet.dev
(exit read-back + independent clearnet oracle). Exit non-payment overhead
dropped from ~50 KiB in / 164 KiB out per session to ~0.

Adds E2E test harnesses (wallet::e2e::funded_e2e_pay,
examples/nostr_split_measure, an exit publish repro in streamexit tests).
