Fix pairing screen on cold restart from Expo Go

Bug Fixes

• Fix pairing screen shown on cold restart from Expo Go (#54, #56)

  • Expo Go caches the initial deep link URL — on cold restart, the same code= from the previous QR scan caused the app to sign out
    the valid session and show the pairing screen
  • Track last redeemed pairing code in SecureStore to skip re-pairing for cached URLs
  • Cache auth tokens in SecureStore adapter to recover sessions when Supabase's internal refresh fails on cold start (network not
    ready)
  • Validate expires_at on sessions returned by getSession() and refresh expired tokens synchronously
  • Skip cached token recovery when a new pairing code is present to avoid restoring old sessions during re-pairing

• Fix mobile server setup (f3ad7c5)

  • Reset local changes before git pull in mobile server setup to avoid conflicts

Improvements

• Auto-detect local mobile project in monorepo — pnpm start from apps/cli now automatically uses the sibling apps/mobile
  directory instead of cloning to ~/.clautunnel/repo/, eliminating the need for clautunnel mobile-setup during development
