- Fixed the subdirectory loading issue.

Changed:
[app/View.php](/Users/tyemeclifford/Documents/GH/blog/app/View.php): 
generated URLs now honor a base path like /blog.
[app/Config.php](/Users/tyemeclifford/Documents/GH/blog/app/Config.php): 
added base_path support and derives it from base_url or SCRIPT_NAME.
[app/App.php](/Users/tyemeclifford/Documents/GH/blog/app/App.php): route 
parsing strips the base path, and PHP can safely serve theme/upload 
assets for virtual subdirectory previews.
[.htaccess](/Users/tyemeclifford/Documents/GH/blog/.htaccess): removed 
hardcoded RewriteBase /.
[themes/neon/layout.php](/Users/tyemeclifford/Documents/GH/blog/themes/neon/layout.php): 
root-relative social links like /feed.xml now become /blog/feed.xml.
[README.md](/Users/tyemeclifford/Documents/GH/blog/README.md): 
documented subdirectory setup.
