fix(#378): poll scoped package name in update check (#414)

The update worker queried the unscoped 'get-shit-done-redux' via
`npm view`, which returns E404 — so `latest` stayed null and
`update_available` could never become true. Now derives the name from
package.json (`require('../package.json').name`) so it always matches
the actual published scoped name (@opengsd/get-shit-done-redux).

Fixes #378.
