Add Bootstrappers section, essays index, specs prose, layout fixes

- New Bootstrappers top-level section with overview index and JS bootstrapper
  page that runs bootstrap_js.py and displays both source and generated output
  with live script injection (full page load, not SX navigation)
- Essays section: index page with linked cards and summaries, sx-sucks moved
  to end of nav, removed "grand tradition" line
- Specs: English prose descriptions alongside all canonical .sx specs, added
  Boot/CSSX/Browser spec files to architecture page
- Layout: menu bar nav items wrap instead of overflow, baseline alignment
  between label and nav options
- Homepage: added copyright line
