feat(reader): glass chrome — translucent bars, custom slider, slide-away hide

Modernize the reader chrome bars without touching the drawer system:

- Bars become theme-tinted glass: 70% bg-primary translucency over
  the edge-to-edge page, 18px backdrop blur + saturation, hairline
  translucent borders, soft directional shadows (single .reader-glass
  class owns the effect; replaces solid opaque backgrounds and the
  tailwind backdrop-blur that would override it).
- Chrome hide/show now slides the bars off-screen (translateY) in
  addition to the opacity fade, via .chrome-hidden on #reader-chrome.
- Theme-aware hover pills (translucent currentColor tint) replace
  hard-coded gray-700 hovers; focus-visible rings added.
- Progress slider gets a custom thin rounded track with a floating
  white thumb (webkit + gecko), replacing native range styling.
- Separators and the fit-mode select match the glass language
  (.reader-sep, .reader-select).
