Public vault configuration

A public vault with ordinary filesystem discovery:

{
  "version": 1,
  "contentDir": "notes",
  "discovery": "filesystem",
  "publication": "public",
  "site": {"name":"My notes","title":"My notes","url":"https://notes.example.com"}
}

Create notes/index.md as the home note. Run bunx twiki dev locally, or follow Static hosting to export it. Private publication is the initial default from init; this example explicitly opts into public access.
