The iOS PKCE login runs in the main-app process, decoupled from the network
extension (the extension's client context is torn down on login-required, which
would otherwise kill the WaitToken goroutine before the OAuth callback arrives).
Because it is decoupled, nothing aborted the flow when the user dismissed the
browser without logging in: WaitToken kept its loopback HTTP server bound to the
redirect port until the flow expired, so the next connect stalled trying to bind
the same port.
Make the Auth context cancellable and add Auth.Stop(), which cancels it. Cancelling
unblocks WaitToken, whose deferred server.Shutdown frees the port immediately. This
mirrors how Android's stopEngine() aborts login via the engine context.
NewAuthWithConfig now also derives a cancellable context; its only iOS caller uses
LoginSync (no interactive server), so behaviour is unchanged there.
* Consolidate authentication logic
- Moving auth functions from client/internal to client/internal/auth package
- Creating unified auth.Auth client with NewAuth() constructor
- Replacing direct auth function calls with auth client methods
- Refactoring device flow and PKCE flow implementations
- Updating iOS/Android/server code to use new auth client API
* Refactor PKCE auth and login methods
- Remove unnecessary internal package reference in PKCE flow test
- Adjust context assignment placement in iOS and Android login methods
* updates to client file writing
* numerous
* minor
* - Align OnLoginSuccess behavior with Android (only call on nil error)
- Remove verbose debug logging from WaitToken in device_flow.go
- Improve TUN FD=0 fallback comments and warning messages
- Document why config save after login differs from Android
* Add nolint directive for staticcheck SA1029 in login.go
* Fix CodeRabbit review issues for iOS/tvOS SDK
- Remove goroutine from OnLoginSuccess callback, invoke synchronously
- Stop treating PermissionDenied as success, propagate as permanent error
- Replace context.TODO() with bounded timeout context (30s) in RequestAuthInfo
- Handle DirectUpdateOrCreateConfig errors in IsLoginRequired and LoginForMobile
- Add permission enforcement to DirectUpdateOrCreateConfig for existing configs
- Fix variable shadowing in device_ios.go where err was masked by := in else block
* Address additional CodeRabbit review issues for iOS/tvOS SDK
- Make tunFd == 0 a hard error with exported ErrInvalidTunnelFD (remove dead fallback code)
- Apply defaults in ConfigFromJSON to prevent partially-initialized configs
- Add nil guards for listener/urlOpener interfaces in public SDK entry points
- Reorder config save before OnLoginSuccess to prevent teardown race
- Add explanatory comment for urlOpener.Open goroutine
* Make urlOpener.Open() synchronous in device auth flow
