Editor tab bar shows Edit/Diff toggle button when viewing a modified file.
Diff view renders git diff output with green (added), red (removed), and
gray (context) line coloring. Uses `get_file_diff` Tauri command.

Replace all hardcoded colors across 10 CSS files with CSS variables defined
in index.css. Dark mode (default) uses the existing navy/purple palette,
light mode uses Notion-inspired warm neutrals from the design tokens
(--bg-primary: #FFFFFF, --bg-sidebar: #F7F6F3, --text-primary: #37352F).
Toggle button (sun/moon) in the sidebar header persists preference to
localStorage. An inline script in index.html applies the saved theme
before React mounts to prevent flash.

Remove native macOS titlebar via decorations:false + titleBarStyle:overlay.
Add -webkit-app-region:drag to panel headers (Sidebar, NoteList, Editor tab
bar, Inspector) with no-drag on interactive elements. Sidebar header gets
78px left padding for macOS traffic light buttons.
