feat: promote ~/.vagrant.d/boxes to a built-in fixed directory (#121)

* feat: promote ~/.vagrant.d/boxes to a built-in fixed directory

* docs(readme): list ~/.vagrant.d/boxes in the built-in global caches table

The supported-ecosystems table names every built-in fixed dir, so the new
Vagrant boxes entry belongs there too.

 ### Added
 
+- Vagrant boxes (`~/.vagrant.d/boxes`) is now one of the built-in global caches, excluded
+  when you opt in with `[fixed_dirs] enabled = true`
+  ([#117](https://github.com/AsimovMac/asimov/issues/117)).
+
 - `[skip_paths]` config section: name directories that Asimov should never search, alongside the built-in `~/.Trash` and `~/Library`. Thanks [@lunaluxie](https://github.com/lunaluxie)!
 
 - `asimov doctor` now checks the data files and reports how many sentinels and fixed directories are loaded, so an incomplete install is diagnosed rather than just failing.

 **Don't see your tool?** You can teach Asimov your own directory + sentinel pairs in a couple of lines — no need to wait for a release. See [Add your own patterns](#add-your-own-patterns).
