The optimistic Connecting paint and the Idle/stale-Connected
suppression lived in the tray's applyStatus, so only the tray got the
smoothed-out transition during a profile switch — the React Status
page (useStatus hook in frontend) subscribes to the same
netbird:status event and was seeing the raw daemon stream, complete
with the Disconnected blink.
Move the policy one layer up into the Peers service, between
SubscribeStatus and the Wails event bus, so every consumer downstream
sees the same filtered stream:
* Peers gains BeginProfileSwitch / CancelProfileSwitch / shouldSuppress.
BeginProfileSwitch sets the in-progress flag and emits a synthetic
Connecting status so both the tray and React paint Connecting
immediately. shouldSuppress swallows the daemon's stale Connected
(peer-count teardown) and transient Idle (Down between flows)
until Connecting / NeedsLogin / LoginFailed / SessionExpired /
DaemonUnavailable indicates the new profile's flow has started,
or a 30s safety timeout fires.
* ProfileSwitcher.SwitchActive calls peers.BeginProfileSwitch when
wasActive (prevStatus was Connected or Connecting) — the only
cases where the daemon emits the blink-inducing sequence. Other
prevStatuses already terminate cleanly on Idle.
* Tray loses its switchInProgress fields, applyOptimisticConnecting
helper, applyStatus suppression switch, and switchProfile's
optimistic-paint call. handleDisconnect now calls
Peers.CancelProfileSwitch alongside cancelling switchCancel, so
the abort path bypasses the suppression filter and the daemon's
Idle paints through immediately.
The full prevStatus -> action / optimistic label / suppressed events
matrix now lives in the ProfileSwitcher struct godoc, with the
suppression-rule-per-incoming-status table on the Peers struct
godoc — together they describe the click-time policy and the
stream-filter behaviour without duplication.
Wails bindings need regenerating to pick up Peers.BeginProfileSwitch
and Peers.CancelProfileSwitch.
