Pipe v0.50.2

The website shows what Pipe is

• New section "A pipe between you and your server" on the website: an animated diagram of commands going to the
  server and alerts coming back, through a valve, a fuse and a gauge, with a language model you can swap
• An animated scene opens "What it does on its own": real commands reach the classifier and split three ways
• Both diagrams are also in the README, in English and Polish. They are plain SVG files and stop moving when the
  system asks for reduced motion
• The website and the documentation are now dark only
• The documentation menu is split into four groups and marks the current page; quotes and "Experimental" notes have
  their own colors
• Corrected the website's limitations: conversations survive a backend restart
