94c0201493 [client] Clear the login-required latch after installing the new client
Run() released the latch before setState() swapped in the fresh connect
client, so Status() calls landing in that window still read the previous
run's context state — which holds the NeedsLogin that prompted the login
— and re-latched what had just been cleared. The generation guard does
not catch this: the clear precedes the observation, so the generation
matches and the store counts as current. The state-change goroutine
calls Status() on every recorder tick, and the login path emits several,
so the window is ordinary traffic rather than a rare interleaving.

Clear once the replacement client is installed instead.

4dd16139ed [client] Fix two concurrency bugs in the Android session binding
Status() read the run loop's label outside any synchronization and then
stored it, so a login or extend completing in that window was undone by
the stale observation, stranding the UI on "login required" over a
healthy session. Guard the latch with a mutex and a generation counter,
and route both clears through the same helper, so a clear that lands
mid-observation wins.

The watch goroutines kept delivering to removed and replaced listeners:
both subscriptions are buffered (one pending tick, ten pending events),
and unsubscribing only stops new items while the loops drain what is
already queued. On Android those callbacks cross into Java, so a
delivery after teardown can reach a listener whose collaborators are
gone. Give each registration a done signal, close it before
unsubscribing, and check it immediately before every callback.

88728dd128 [client] Expose the SSO auth session to the Android binding
The Android client had no way to see or refresh the peer's SSO session:
the core tracked the deadline and published expiry warnings, but none of
it was exported, so an expired session surfaced only as a raw error
string from the engine run loop.

Mirror the surface the daemon serves its tray:

- Status() and SessionExpiresAtUnix() report the run-loop status label
  and the tracked deadline, the two values StatusResponse carries.
- StateChangeListener signals state changes (payload-free, consumers
  re-read the getters) and forwards the session-expiry warnings from
  the engine's watcher, filtered out of the shared event stream.
- ExtendAuthSession() runs the interactive SSO flow and refreshes the
  deadline without touching the tunnel, with CancelExtendAuthSession()
  for an abandoned browser round-trip — its PKCE wait would otherwise
  hold the loopback port until it timed out and block every retry.
- DismissSessionWarning() suppresses the final warning.

Status() latches NeedsLogin: the run loop keeps its status in a
per-run context state that a restart replaces with a fresh Idle one, so
an engine restart would otherwise erase the fact that the peer still
needs to log in. Only a successful login or extend clears it.

24287577c8 [client] Cover both invalid-ID orderings in the partial-error test
The partial-failure test only placed the unknown ID after the valid
exit node, so it never verified that selection processing continues
past a leading invalid ID. Run the same assertions for both orderings.

7e1b35037a [client] Keep exit-node exclusivity on select-all and partial errors
Selecting all routes wipes every explicit selection, so exit nodes fall
back to management's auto-apply flags, which may mark several at once.
Reconcile immediately after select-all so at most one stays active
instead of waiting for the next network map.

A partial selection failure (e.g. an unknown ID in the request) still
selects the valid routes, so run the sibling exit-node deselection
regardless of the error and report both failures together.

cc0ab3247d [client] Unify route selection in the route manager
Move route select/deselect handling from the daemon server into exported
routemanager methods (SelectRoutes, DeselectRoutes, SelectAllRoutes,
DeselectAllRoutes) so every consumer shares one implementation: v4/v6
exit-pair expansion, exit-node mutual exclusion, and selection triggering.

Previously the exit-node exclusivity lived only in the daemon's
SelectNetworks RPC, so the Android and iOS bindings could leave two exit
nodes selected until the next network map reconciliation. Both bindings
now call the shared manager methods and enforce exclusivity at toggle
time, matching the desktop behavior.
