Bring the org-ssg templates to parity with the live site

The org-ssg build rendered the right content in the wrong chrome. Closing every
difference found by comparing it against theme/templates/ and the live pages:

- base.html: Home link written by the layout rather than the site title, a
  <title> of "Page - cleberg.net" (bare "cleberg.net" on the home page, via a
  subtitle block), author/description/og meta, the RSS alternate link, four
  rel="me" identity links, favicon, skip link, <main id="main-content">,
  aria-label on the nav, and the real footer.
- home.html: the h1 is "Christian Cleberg" (the collection's title), and the
  email line has its GPG link back.
- blog.html and garden.html: the two listings carry their own prose on the live
  site — the search/RSS hint, and the garden's growth stages — so they are no
  longer sharing the generic list.html. Tag pages still use it.
- tags.html: "Browse posts by topic."
- Blog posts get the reply-by-email and Bubbles lines. org-ssg has no per-page
  template selection, so the layout keys off the page's URL prefix.
- Tags leaves the nav, which the live site does not have.

feed.xml is new: the footer links /feed.xml and nothing was generating it. It
is a collection whose template happens to be XML. Its <description> carries
each post's excerpt rather than the full rendered body, which weblorg's feed
does include — a collection template gets each entry's metadata, not its HTML.

base_url is now set, since canonical links and a feed cannot be relative. Page
links stay relative, so a preview build still works from any directory.

gpg.txt, robots.txt and salary.csv are copied in from theme/static/: weblorg
publishes that directory to the site root, and org-ssg publishes from content/,
so /gpg.txt was a 404. styles.min.css is deliberately not copied — it is
gitignored build output, and the tracked styles.css holds the same rules.
