Reader 1.2.0

Reading

• Code blocks render as full-width bands with 16pt horizontal and 10pt vertical padding (custom NSLayoutManager fills line fragments instead of glyph hulls)
• Opening a file (Finder double-click, ⌘O, Recent) drops straight into preview mode; ⌘N stays in edit mode
• Dark mode page and chrome are now pure #000

Fixes

• Preview mode strips ``` fences correctly
• Window resize no longer wipes formatting in preview (restyle now no-ops while previewing)
• NSRangeException hardening: every selection-derived NSString call site clamps to bounds
• Bold button no longer lights up on heading lines (format-state probe now scans markdown markers in the line prefix, not font traits)
• Titlebar/content separator line removed (titlebarSeparatorStyle = .none)

New

• reader CLI — ./scripts/install-cli.sh drops a symlink into /usr/local/bin or ~/.local/bin; run reader path/to/file.md from anywhere
