reboot-plugin

Upgrade an existing Reboot application to the latest Reboot version. Use when `rbt` prints "A newer Reboot (X.Y.Z) is available", when an application refuses to start because its `reboot` version does not match the `rbt` CLI, or when the user asks to upgrade/update Reboot. First talks the developer through updating the plugin itself when it is out of date, then applies the migration steps each intermediate release needs, bumps every version pin to the exact version the plugin ships, regenerates code, and runs the tests.
