Overview
Aligns the pre-React boot shell and browser chrome with the app’s current dark workspace background by replacing #161616 with #0a0a0a.

Updates dark theme-color meta tags, the inline boot script’s DARK_BACKGROUND, and html.dark body background so the splash screen no longer flashes a lighter gray before React mounts. Light mode stays #ffffff.

Fix dark mode loading screen background color to match app theme

Updates the dark mode background color in index.html from #161616 to #0a0a0a to match the app's dark theme. Changes apply to the theme-color meta tag, the DARK_BACKGROUND bootstrap script constant, and the html.dark body CSS rule.
