feat(reader): redesign ArticleReaderView + global appearance toggle

Reading experience:
- Body text #CECECE (dark) / #1A1916 (light) — was near-invisible #4A4A4A
- 30pt heavy headline, 17pt body at 8.5pt line-spacing
- Skeleton pulse loading state replaces dark spinner box
- Hero image fades in on load (0.3s ease-in)
- Orange reading progress bar (2pt) below nav bar
- Max reading width 680pt for iPad legibility

Appearance:
- AppearanceMode enum (system/light/dark) in Theme.swift
- @AppStorage("appearanceMode") applied once in JarvisApp root
- Appearance picker (Picker in Menu) in reader toolbar
- Removed .preferredColorScheme(.dark) from all 12 child views
