capsite/potluck: a weekly zine of issues, not a blog

- issues collection (ISO-week slug, week, dek, rich-text body); home,
  /issues, and /issues/<week> pages; seed/issues.json holds three
  sketched issues (W38-W40) from public diigo bookmarks, editorial
  lines marked (draft); issues-sketch.md is the dry run behind them
- microformats: h-feed of h-entry lists; an issue is an h-entry
  (p-name, dt-published, p-summary, e-content); off-site links render
  as h-cite, /tag/<tag> links as rel-tag p-category (CiteLink.astro)
- diigo tags: shown on each bookmark and attached to issues via the
  tag taxonomy (now posts + issues); /tag/<tag> lists issues
- demo blog content gone: posts dropped from the seed, home page lists
  issues, site title/tagline, footer About widget, and About page
  rewritten; nav is Home / About / Issues; search and RSS cover issues
- .column container gives potluck's pages the header's margins
