Core Rule Set: MediaWiki's ordinary requests pass by default (closes #237 )

Adds mediawiki.conf, the eleventh change: on MediaWiki's paths, the fields that carry a search, a title, a name, a file name or an address skip the four rules that read them as commands or system files, and the wikitext fields skip the rules that refused saving a page. The reasons on the admin pages skip only 930120 and 932120. /index.php counts as MediaWiki's only with a page title in its query or after its path, since WordPress serves it too. The requests recorded from MediaWiki 1.46.2, with and without short URLs and on the admin pages, pass at the defaults and while bodies are read. The app tests share the check of recorded requests and the list of hard values. Model: opus-5-5

   `Referer` names the page a request comes from, on everything that page loads
   and on every link followed from it. The Core Rule Set takes some page
   addresses for attacks:
    - a search for `env`;
    - OpenJDK's `Runtime.java`, whose path holds both `runtime` and `java.`;
    - a file named `java.lang.String.md`.
    Every request from such a page would be refused. `Referer` keeps the other
    rules, except after some gitea searches (gitea's fixes). An app that passes
    `Referer` to a shell must check it itself.
 5. Responses are not inspected. A raw file from a repository, such as a shell
   script, looks to the response rules like source code leaking from the server.
 6. The `from` parameter of a container registry's upload path,
   `/v2/<image>/blobs/uploads/`, is not checked for command names (932260). When
   a push reuses a layer, `from` names the image the layer comes from. An image
   such as `owner/python3-app` would have that push refused.
 Each supported app also has its own fixes, which let its ordinary requests
 through. `SWW_APPS` says which hostnames get which app's fixes:
 - `SWW_APPS` holds entries separated by semicolons. Each is a hostname, a colon,
  then one or more apps separated by commas, for example
  `git.example.com:gitea;blog.example.com:wordpress`.
 - The request's `Host` is matched by exact name, without its port and without
  regard to case. There are no wildcards.
 - A hostname not listed gets no app's fixes, so every rule checks it in full.
  Set empty, `SWW_APPS` lists no hostname.
 - Unset, every app's fixes hold for every hostname. An app's fixes then weaken
  the check of any other app that serves the same paths or fields.
 - Any of these mistakes stops the start:
    - an unknown app;
    - a hostname that is not a DNS name, such as `*.example.com`;
    - a hostname listed twice;
    - an app listed twice for one hostname;
    - an entry without a colon.
