hermes: use the vector mark everywhere, retire the raster paths

User supplied the real vector source at Hermes/Icons/file.svg. Dropped the
background rectangle, kept the sky-blue foreground + dark inner detail
cutouts, squared the viewBox around the content bbox with a small margin.
Result: ~6.6 KB SVG, pixel-perfect at every size — no more 60x downscale
blur.

- bundled-addons/hermes/assets/mark.svg: tight-cropped vector
  (viewBox centres the icon in a square so 1:1 slots don't crop).
- bundled-addons/hermes/assets/mark-64.svg: same, pre-normalised to a
  0..64 viewBox for legacy consumers that assume that range.
- bundled-addons/hermes/addon.json: version 0.2.4; manifest icon is now
  the SVG as a data:image/svg+xml;base64 URI (8.8 KB vs the previous
  16 KB PNG data URI).
- bundled-addons/hermes/panel.html: both img tags point at mark.svg at
  24 and 72 px.
- home.html / home-brand/hermes-mark.svg: Hermes.X tile uses the vector.
- site/hermes/{favicon,branding/mark}.svg: both now the user's artwork.
- site-hermes-x/assets/{favicon,mark}.svg: same.
- All /hermes site HTML img tags swapped from mark.webp to mark.svg.

Installed bundle + user-data cache hot-patched to 0.2.4 so this takes
effect on the running Theseus without a reinstall.
