v0.3.1: CSS jetzt extern via <link> statt JS-injected

Drei Probleme mit der JS-Injection:
1. CSS kommt NACH First Paint → User sieht kurze obv-Layout, dann 'springt'
   zu responsive Layout (FOUC = Flash of Unstyled Content)
2. JS-Injection kann fehlschlagen (head nicht ready, Browser-Inkonsistenzen)
3. Inline <style>-Tag wird nicht gecacht, lädt bei jedem Reload

Fix: hermes-custom.css als separate Datei, geladen via
<link rel='stylesheet'> im HEAD. Server liefert sie automatisch.

Außerdem: Mobile-Mode zeigt Graph als Bottom-Panel (140px), nicht mehr
display:none. User behält Wiki-Beziehungen auch auf Phone.

vault-custom.js.js behält injectResponsiveCSS als no-op für Backward-Compat.

+ * Layout classes (toggled by vault-custom.js):
+ *   .hermes-rc               — base marker (added once)
+ *   .hermes-mobile           — <768px viewport (tree=hamburger, graph=bottom-panel)
+ *   .hermes-tablet           — 768-1023px (tree=visible, graph=bottom-panel)
+ *   .hermes-desktop          — >=1024px (3-panel layout, no overrides)
+ *
+ * Sidebar state:
