/**
 * Auto Theme Extension
 *
 * Syncs pi theme with the OS dark/light mode, switching between paired
 * dark/light themes.
 *
 * Mode detection per platform:
 *   macOS:   polls appearance via osascript every 3 seconds
 *   Linux:   polls `mode` in Omarchy's colors.toml (~/.local/state/
 *            omarchy/current/theme/colors.toml), which omarchy theme
 *            set refreshes. Inert without Omarchy — an unreadable mode
 *            never resolves to "light" and stomp paired themes.
 *   other:   inert
 *
 * Theme pairs:
 *   nightowl        ↔ lightowl
 *   tokyonight-night ↔ tokyonight-day
 *   catppuccin-mocha ↔ catppuccin-latte
 *   dark             ↔ light
