v0.15.0

Changed

• The content health page is ordered by priority: Fix now, Fix next,
  Improve, Tidy up, and the proposed title convention last, which is
  not required yet. Every group of findings, whether a check, a reason a file
  is not on the site or a note, sits under one of them, each in its own color
  with an icon and a label, quieter as the priority falls. See
  ADR-037, which
  supersedes ADR-024 and ADR-028 in part, and ADR-011 in part for status
  colors on this page.
• The page opens on the whole knowledge base: the number of files in the most
  urgent state, with a link to them, how many files are on the site, and a bar
  of every file by its most urgent task, its states named apart from the
  priorities. "Where the work is" follows: tasks by section and by last
  editor, and choosing a row filters the page to it.
• A group is folded to one line, what it is, what to do, how many files and
  where, except under Fix now; within a priority, files not on the site come
  first under their own heading, and the largest group first. A file leads with
  "Open in Google Docs" or "Open in Google Drive"; its page is a quieter link.
  A letter typed in the other alphabet is named in words and marked in its
  heading. The checks that were all clear are listed under their priority.
• The section and editor filters sit in a toolbar that stays at the top of a
  wide screen, with a chip per priority, and narrow every task list and count.
  The address keeps the filter, a filtered view offers to copy its link, and
  such a link opens on the tasks, unfolded when there are 15 or fewer.
• The old section anchors #not-on-the-site, #notes, #fix, #convention
  and #note are replaced by #fix-now, #fix-next, #improve, #tidy-up
  and #proposal. A group keeps its own anchor.
• Each title check carries a short action, as reasons and notes do, written to
  data/title-report.json. The page leaves it out for a report written before.

Added

• --kb-red, --kb-orange, --kb-blue, --kb-green and --kb-purple, with
  a -low step each, read in the adapter from Starlight's aside palette, which
  sets them per theme. Only the content health page uses them.

Removed

• HealthSummaryTable.astro: a group's folded line replaces its row.
