About reported four component versions and, since this morning, a short hardware summary. It now covers what someone actually wants from an About page or a fastfetch run: operating system, model, hostname, kernel, uptime, package counts, shell, locale, windowing system, resolution, processor, graphics, memory, swap, and disk. Rows are ordered the way fastfetch presents them -- what the system is, then what is installed on it, then the hardware underneath -- and the GPU rows are spliced in directly after Processor rather than appended, because a graphics card listed after "Disk" reads as an afterthought. Graphics is still joined from GraphicsDevices rather than read a second time, so the two readouts cannot disagree. Memory is total, not used. About is not a monitor: a "12.4 GiB used" figure is stale before it finishes drawing, and the Home page's vitals readout is where live numbers belong. Disk is the exception because free space does not move while you look at it. Package counting is why this whole helper runs on demand -- rpm -qa on a full workstation is a few thousand lines and takes a moment. Swap and package counts are omitted entirely when they are zero or the tools are absent, rather than reported as "0" or "Unknown".
