Relay connect used to serialize a dead LAN probe (up to 8s per stale address
on mobile, 2-4s on desktop) in front of the relay attempt, then paid a second
WebSocket connect + E2EE handshake because the probe tunnel was thrown away.
- mobile probeConnectionCandidates: race the relay probe against the direct
chain with a 1.5s direct headstart; a live LAN still wins, a dead one no
longer delays startup
- relay probes adopt their tunnel as the runtime tunnel (adoptRelayTunnel)
instead of dialing a fresh one — applies to auto-connect, pairing redeem,
password login, and the desktop host switcher's relay fallback
- relay probe drops the /health round-trip: the E2EE handshake already proves
the server identity, /auth/session alone proves liveness and auth
- desktop restoreDesktopRelayRuntime: same headstart race; a late direct
success hot-switches back (stable runtimeKey); startup probe now passes
expectedServerId so a re-leased LAN address never sees the token
- launch splash shows 'Connecting to device: <label>' with animated dots
under the (still centered) logo, translated in all locales
- editing a saved instance no longer rebuilds it from the URL field alone:
the id is passed through, relay/https candidates are preserved, and a
token-key change migrates the Keychain token instead of orphaning it
