The UI never needs to block on Up — status updates flow via the
SubscribeStatus stream. Hardcode Async:true in Connection.Up and remove
the Async field from UpParams so frontend callers are unaffected.
Down and Up(async=true) are both fast RPCs; no background goroutine
is needed. SwitchActive is now fully synchronous — the tray wraps the
call in its own goroutine, and Wails handles React calls similarly.
Switch RPC errors are now returned synchronously to the caller so the
tray can show a toast immediately on invalid-profile or other early
failures. Down and Up run in a background goroutine so the caller
returns fast; Up still uses async=true so the goroutine is short-lived.
The daemon's Up RPC previously always blocked in waitForUp (up to 50s)
until the engine connected. The UI does not need this — status updates
already flow through the SubscribeStatus stream.
Add bool async = 4 to UpRequest. When true the daemon starts
connectWithRetryRuns and returns immediately; the CLI path (async=false,
the default) is unchanged.
ProfileSwitcher.SwitchActive now sets Async:true so all three RPCs
(Status, Switch, Down, Up) return quickly. The background goroutine and
its associated race condition are removed entirely.
Both the tray and the React Profiles page previously had separate
switching logic: the tray applied a status-aware reconnect policy
(Down for error states, Up only when previously Connected/Connecting),
while the React page always called Switch + Up unconditionally with no
Down for LoginFailed/NeedsLogin/SessionExpired.
Introduce a single ProfileSwitcher service that encapsulates the full
reconnect policy. SwitchActive queries the current daemon status, calls
Switch, and launches Down/Up in a background goroutine so the caller
returns immediately after the Switch RPC completes. Both the tray and
the React Profiles page now delegate to this service.
Export the daemon status string constants (StatusConnected, etc.) from
the services package so tray.go no longer duplicates them as private
constants.
