The directory name is what the status bar and the launcher cards display, so Home, Hello and Settings read as titles without a lookup table. Updates the firmware's home path, the launcher's self-exclusion and the host tests that load the settings app. Also brings the bar's next repaint forward when an app renames itself or the frame rotates. The bar still decides what changed; this only stops the answer waiting most of a second for the next tick.
