Upgrade Fah Swe RTC tooling

Upgrade

Run the installer with the newer archive and its manifest. The previous binary is kept as a .prev copy so you can roll back.

Check an update

update check/apply work from a local manifest and archive only; the CLI does not download updates by itself.

fahswe-rtc update check --manifest ./release-manifest.json --json

Roll back

fahswe-rtc update rollback
