Frist, this

     # www redirect
     if ($host ~* www\.(.*)) {
         rewrite ^(.*)$ https://domain.tld$1 permanent;
     }

should be written as separate server:

server {
     server_name www.domain.tld;

     rewrite ^(.*)$ https://domain.tld$1 permanent;
}

Second, "set" in

     set $web_root /usr/local/www/main;
     ...
     root $web_root;
     ...
         fastcgi_param SCRIPT_FILENAME $web_root$fastcgi_script_name;

is just waste of CPU cycles and should be changed to

     root /usr/local/www/main;
     ...
         fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

As to wiki, you need to omit "=":

     location /wiki/ {
         alias /usr/local/www/skittles_wiki/;
     }
