Patrick Ecord 3d4af095b1 wasm: browser↔native clipboard sync works over iroh ...

Two root causes kept the wasm web client from syncing with native peers,
both fixed here:

1. Gossip island — a node that registered with the rendezvous first joined
   its gossip topic alone and never pulled later-joining peers into its
   active view (its single subscribe_and_join was done, so a browser that
   appeared afterwards had a live magicsock path but no gossip neighbor).
   The re-register loop now seeds peer relay addrs into the MemoryLookup and
   calls GossipSender::join_peers each round, so neighbors form both ways.

2. Engine::send panicked on wasm — directly_covered() calls Instant::now(),
   which traps ("time not implemented") on wasm32-unknown-unknown, so send
   threw before ever reaching the gossip broadcast (0 Broadcast commands).
   web-time backs Instant with Performance.now() on wasm; native keeps
   std::time and is unaffected (web-time isn't linked there).

Supporting connectivity: the rendezvous now stores + returns each peer's
iroh relay URL (PeerInfo{id,relay}) so a browser — relay-only, can't resolve
id→addr via discovery — can dial natives via a seeded MemoryLookup; CORS
added so the browser's fetch to the rendezvous is allowed.

Verified live, cross-relay: text typed in a browser tab lands on the Mac
clipboard and vice-versa, with the wasm engine running as a relay-only iroh
peer. Browser-console tracing capped at INFO; demo send wrapped in try/catch.
