Add sidecar update check on startup
On launch, after confirming the sidecar is installed, the app now
checks for a newer sidecar version via the Gitea API. If an update
is available, shows a prompt with "Update Now" or "Skip":

- Update Now: shows the SidecarSetup download screen
- Skip: launches the existing sidecar version

The update check is non-blocking -- if it fails (no internet, API
error), the app silently proceeds with the current version.
