Remove the app title from the header

The window title already names the app. Hide the "mpckit" heading
visually (screen readers keep it) so the project name starts at the
left, and show the "Project name" label at every width.

 **Change after the first laptop run** (bajdev, 2026-11-12: the Windows build runs): About showed the commit id instead of 0.5.0, because the first version of the stamping used `git describe --tags` and there are no tags yet. It now shows the version from the Taskfile, with the commit on its own "Build" line.
 
+**Header change** (bajdev, 2026-11-12): the "mpckit" title next to the project name isn't needed (the window title already says mpckit). The visible title is removed, so "Project name" and its input start at the left. The title stays as a heading for screen readers. With the extra room, the "Project name" label now shows at every window width (it used to hide below 1100px).
