longecho 0.6.1

Fixes from an independent code review of 0.6.0.

Fixed

• build no longer recurses forever, or crashes, when contents lists the
  directory itself (path: .) or a symlink loop, or when a symlink points
  back up the tree. A source never appears as its own sub-source.
• build refuses a site/ that is a symlink to the archive, even with
  --force; it used to overwrite the archive's own README.
• One malformed link in a README (such as http://[) no longer stops the
  whole build; the link is dropped and the text kept.
• A bare <embed> in a README no longer hides everything after it.
• Frontmatter with a YAML set, a binary value, a date used as a key, or
  keys of mixed types no longer crashes build or query --json. Every key
  becomes the string JSON would use.
• check, query, and build no longer crash on a README, or a
  subdirectory, behind a symlink into a directory they may not search.
• query --table no longer crashes, or styles text, when the path contains
  Rich markup such as [/bold].
• A short file ending in a cut-off UTF-8 character now counts as binary and
  is warned about.

Changed

• File entries in contents are now purely informational, as documented: a
  contents that names no directory leaves sub-source discovery automatic.
  Before, listing only files hid every subdirectory from the site. A
  directory entry that is skipped (the directory itself, or a path outside
  it) still makes the list curated.
