Auto-update banner

Step diagram

Update channel polls in background
App
App calls the configured update channel periodically; default ON for Koder products.
Silent download to staging dir
App
If a newer release is available, the SDK downloads the platform-native package to a staging directory without interrupting the user.
Banner appears
User
When the download finishes, KoderUpdateBanner surfaces non-blocking at the top of the active screen.
User taps Restart
App
App swaps to the staged release and re-launches preserving session state where possible.
Resume
User
Same screen, new code. Auth context, navigation stack, and form drafts are preserved when the SDK supports it.

Showing a modal instead of the banner — interrupts the user mid-task and feels like a system update.
Restarting without saving form drafts — loses unsubmitted user input.
