v0.9.0

Added

• The content health page at /content-health/. It groups what editors have
  to fix by the action that fixes it, with an instruction for each check.
  Each document links to its page and to Google Docs, at the line concerned
  when there is one. Filters narrow the list to one section or to whoever last
  edited the document. It is not in the sidebar or in search. See
  ADR-024.
• Checks in the title report:
  • a heading that mixes alphabets, now read from the source with a link to
    it;
  • a document that opens with another document's title;
  • an empty document;
  • the proposed one-Title-line convention (title styled as Heading 1, no
    title line, title not first, Title style on a section);
  • Drive names with "Copy of", a file extension, underscores or extra spaces.
• The sync's job summary lists the checks as counts, with a link to the page.
• Who last edited each document, from Drive's lastModifyingUser display
  name.
• ctcdocs-sync validate fails when the project's Prettier configuration
  would format a generated path, and names each one to add to
  .prettierignore. It asks Prettier itself, reading .gitignore and
  .prettierignore the way prettier --check . does, and it checks every
  path the allowlist names whether or not the sync has written it yet. A
  project that listed generated files one by one did not ignore
  data/title-report.json after 0.8.0, and learned so only when a full sync
  had exported everything and then failed its format check.

Changed

• content-health is a platform route.
• The title report moves to schema version 2. It lists its checks, and each
  document lists its issues, section and last editor. Facts recorded by 0.8.0
  count as not inspected: run a full sync once after upgrading.
• Title similarity takes the better of character edit similarity and shared
  words, and a reordered title is classified as reordered.
• The Docs API request also reads each paragraph's heading ID.
• @ctcstack/ctcdocs-sync declares prettier 3 as a peer dependency. Every
  project already installs it for its format check; validation now uses the
  same copy, so the answer is the one the format check would give.
• @ctcstack/ctcdocs declares prettier 3 as a peer dependency as well. It
  ships the shared Prettier configuration, so it always needed one; the
  requirement is now stated rather than assumed.
