I went and read:

https://pause.perl.org/pause/authenquery?ACTION=pause_namingmodules

Realized I should probably not name this something with an inscrutable
top-level namespace.  WRT is still inscrutable, I guess, but at least
it's now under App.

- Renames all modules, fixes tests (such as they are)
- Zaps old t/validate/ stuff

- adds include_process() in WRT::Markup
- moves eval_perl() into WRT::Markup.  The way object instances are
  composed (and instance methods called) here still feels pretty janky,
  and this does nothing to help the situation.
- changes all existing $root_dir instances to $entry_dir; adds a $root_dir
  which represents the root of the archive (top-level folder containing
  the wrt.json file)

I'd be worried about the $root_dir change if I thought this module had a
single other user in the wild, but I strongly doubt that it does.  If I
am wrong and you are that user, I apologize sincerely in advance.

The include feature still has fairly unsettled semantics, but it gets the
whole thing much closer to a usable site generator.

It's shorter and the letters are all right there on the keyboard.

...also test that it'll render a snippet.

Moar memory, less potential confusion doing it in place.

Also made it send errors to the log instead of displaying them.
