Add the Feuerwerk logo files and a favicon for the editor

The project has a name and a logo now, but neither the editor tab nor
the repo carried it. The logo existed only as a design mockup.

- public/brand/ holds the logo in three layouts: the icon alone, the
  wordmark to the right and the wordmark below. Each comes in a light
  and a dark variant, with a transparent background.
- The geometry is taken from the mockup. Strokes are rebuilt as filled
  shapes. The wordmark is Manrope Bold converted to paths, with the
  font's kerning and -0.03em tracking, so no installed font is needed.
- The favicon is the dark icon on a rounded #15171B tile, as SVG plus
  favicon.ico (16, 32, 48 px) and a 180 px apple-touch-icon. Only the
  editor page links it. play.html shows the games and stays without.
- nginx serves the folder as /feuerwerk/public/brand/. Vite has no
  publicDir, so the files are not copied into dist/.

Findings:
- At 16 px the strokes get thinner than one pixel and the icon blurs.
  From 32 px on it is clean.

Tests:
- Rendered in Chromium at 3x against the mockup: the icon matches to
  7 of 255 per channel, wordmark edges sit within 1 device pixel.
- Prettier on web/index.html clean. No full gate, the change has no
  code in it.
