The friends-only presence listener (W7) must answer pings while the app is
open, whether or not we're in a call — but a node id has exactly one live
endpoint instance (proven by the dual-endpoint spike: two endpoints sharing a
SecretKey collide, all inbound connections land on one and the other's ALPN
fails the QUIC handshake). So the listener can't get its own endpoint; the
whole app must share one persistent endpoint. Today the core rebuilds the
endpoint+gossip+router on every Join and tears them down on leave, so there's
nothing alive between calls.
B1 hoists those durable pieces to the app lifetime (no new behavior):
- New persistent `NetStack` (endpoint + gossip + Router) built once at startup
under the RelayNoDiscovery default (relay reachability, no DNS beacon);
`online()` is backgrounded so launch isn't blocked.
- New persistent `AudioRouter` (src/network/iroh_impl.rs) replaces the
per-session `AudioProtocol`: it's registered once on the single Router and
delegates each inbound audio connection to whatever session `Shared` is bound
(`bind` on join, `clear` on leave), dropping links when idle. `IrohTransport::
new` now returns just `Self`.
- Join reuses `net.endpoint`/`net.gossip` and only subscribes its gossip topic +
binds the audio router; Leave clears the router but keeps the endpoint up.
- `SetNetworkMode`/`RegenerateIdentity` rebuild the stack immediately when idle,
else defer to the next Leave/Join (preserves "applies on next join"), and the
existing session is always torn down before any rebuild closes the endpoint.
Tests/loopback updated for the new transport API. 256 lib + 6 reconnect + 4
loopback + 2 ignored real-endpoint tests green, clippy --all-targets clean,
release builds. NOT yet 2-machine field-verified — that regression is the gate
before this merges to main.
