Subject: [PATCH] refactor(auth): remove dead AuthReset event
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

AuthReset was declared in the AuthEvent union and handled in
auth-machine.idle.on with `assign(() => initialState)`, but
nothing in the codebase actually dispatches it anymore.

History of dispatch sites (now all gone):
- sidebar-screen.tsx previously dispatched AuthReset post-logout
  alongside router.replace(ROUTES.chat) — that was simplified to
  just dispatch AuthLogoutSubmitted, the state machine's
  loggingOut state now does the context reset itself in onDone
  via the same `assign(() => initialState)` action.
- chat-screen / splash / auth screens never dispatched it.
- The /auth screen's pendingRedirect-based redirect loop doesn't
  need it (the redirect is one-shot, not a state that needs
  resetting).

So the event handler is unreachable. Remove the type member
from auth-events.ts and the handler from auth-machine.ts.

No behavior change: the only path that 'reset auth state' was
already covered by loggingOut.onDone.

Verified via `grep -rn 'AuthReset' src/`: only 2 hits remain
after this commit — both are the type declaration and the
machine handler, which is now also gone (zero hits).
