Accent CMS v0.27.3

A bug-fix release for the v0.27 line. It fixes nine bugs: site search listed
pages of every language, from a search form and from the search island;
redirect pages appeared in the sitemap, the search index, llms.txt and the
feeds; a configured taxonomy without its own templates listed the tags;
accent validate counted a component finding's line from the body, not the
file; accent serve allowed scripts for search and diagrams a site turned
off, redirected a static/ file under a versioning root that the build
publishes, and did not revalidate links when static/ changed; and
diagrams.enabled: false did not reach the {% diagram %} tag or
diagram().

Cut from the release/0.27.x maintenance branch rather than from master,
so anyone whose licence ceiling is 0.27 can take it.

Changed

• diagrams.enabled: false turns off every diagram surface. The switch
  removed only the fenced-block processor: a {% diagram %} tag and a
  diagram() call in a template still rendered, as an SVG in the build and
  in dev serve as markup for the browser loader. Since the dev server no
  longer allows the Mermaid CDN on a site with diagrams off, that page showed
  the bare source in dev. Both now render their source in a code block, in
  the element and class a fenced block gets, in accent serve and
  accent build. A site that turned
  diagrams off and still wants the tag or the function to draw diagrams
  turns them back on.
• New keys in the taxonomy template context. Every taxonomy page, the
  tag pages included, carries taxonomy.name and taxonomy.singular (tags
  and tag, or a configured taxonomy's), taxonomy.terms (that taxonomy's
  term list) and, on a term page, taxonomy.current_term (the term's
  lowercase name). On other pages name and singular are none and terms
  is empty.
• Taxonomy names that collide with a context key are rejected. A
  configured taxonomy named name, singular, terms, pages,
  current_term, current_label or current_tag, or with the singular
  label, or named after a taxonomy's current_<singular> key, its own
  included, is now a configuration error. Its keys would replace the
  context's own: taxonomy.pages and taxonomy.current_label already
  collided before this release. Rename the taxonomy, or its singular.
• The search island holds a search form. The search island had a search
  client of its own; it now holds the form search_form() renders and loads
  the site's search script when it hydrates. Its results, messages and
  keyboard handling are those of every search form, DocFind included. In a
  template, put {{ search_form("Search...", 5, script=false) }} inside the
  <accent-island data-component="search">: the new script=false leaves
  the script to the island. An island:search block renders the form itself
  and takes placeholder, max_results, no_results, results_label and
  all_languages. The props endpoint, min_chars and debounce are gone:
  the island reads the site's own index, and endpoint also missed the
  deployment prefix. Results use the form's .acms-search-* classes, so a
  theme that styled .island-search-results or .search-hit styles those.
  A hand-written form inside a search island no longer searches: replace it
  with search_form(..., script=false).

Fixed

• accent serve revalidates links when static/ changes. The link check
  reads the passthrough directory, but the hot-reload watcher did not watch
  it, so adding a file there to fix a broken link left the finding in the
  admin and MCP reports until an unrelated content edit, and removing one
  left its links reported as fine. The watcher now watches the directory and
  rebuilds the content index on a change there, and the browser reloads.
• A static file under a versioning root is served at its path. On a site
  versioned under /docs, accent serve answered a request for
  /docs/a.pdf, the URL of static/docs/a.pdf, with a redirect to the
  default version, /docs/v1/a.pdf, where nothing answered, while
  accent build publishes the file at /docs/a.pdf. The server now serves
  the file there, as the build does.
• Component findings name the line of the file. accent validate, the
  admin validation report and the MCP validation resource counted a
  component finding's line from the first line of the page's body, so a
  finding pointed as many lines above its tag as the frontmatter was long. A
  finding inside a ---section: region was counted from the section's
  marker. Both now name the line of the page's file.
• accent serve allows scripts only for features the site runs. The
  served script-src named 'wasm-unsafe-eval' whenever the search backend
  was DocFind, on a site with search.enabled: false too, and in dev the
  Mermaid CDN origin with diagrams.enabled: false. On such a site the
  build's header artifacts named neither, so a page tested locally ran under
  a wider policy than the one deployed. The server now adds each source
  only when the feature is on, and decides 'wasm-unsafe-eval' as the build
  does.
• Site search keeps the results in the reader's language. On a site with
  two or more site.languages, search listed the pages of every language,
  so a reader on an English page got German results, and Enter could open
  one. A search form now lists the pages in the language of the page it is
  on, with Simple Search and DocFind, in accent serve and accent build,
  and the result limit counts the results after scoping. The form's empty
  message and the name of its results list were English on every page:
  search_form() now takes them as no_results and results_label, and the
  {% search %} tag as attributes of the same names, so a theme passes them
  in the page's language. To list every language, pass
  all_languages=true.
• Redirect pages are in no index. A page with redirect: was listed in
  sitemap.xml, in the search index of both backends, in llms.txt and
  llms-full.txt, in the feeds when it had a date, and on tag and other term
  pages when it had terms, although its URL serves no content. Search listed
  each stub as a result with nothing to show, and the sitemap of every site
  from accent init listed /, which redirects to /home. A translation
  that redirects was also named as an hreflang alternate, in the sitemap and
  in the head of each sibling page, and listed in page.translations, which
  drives language switchers.
  These outputs now leave a redirect page out, in accent serve and
  accent build, as content collections already did. noindex: true still
  does not reach site search; search.exclude leaves a page out of it.
• A taxonomy without its own templates lists its own terms. A configured
  taxonomy whose theme has no <name>.html.jinja renders through
  tags.html.jinja, which listed taxonomy.tags, so /categories showed the
  site's tags, and its term pages linked back to /tags. Every taxonomy page
  now carries taxonomy.name, taxonomy.singular, taxonomy.terms and, on a
  term page, taxonomy.current_term, which name the taxonomy being rendered
  on the tag pages and on a configured taxonomy's alike. The starter's and the
  default theme's tag templates use them, so they render every taxonomy. A
  theme of your own that relies on the fallback lists the tags until its tag
  templates do the same: list taxonomy.terms, link through
  term_url(taxonomy.name, term), and compare with taxonomy.current_term.
• The search island keeps the results in the reader's language. On a
  site with two or more site.languages, the search island listed the pages
  of every language, and its empty message and results label were English.
  It now scopes its results and takes its texts as every search form does.
• The search box of accent serve <dir> names the backend the server
  serves. It named Simple Search while the server served DocFind; both
  worked, because the Simple index is always served. It now loads DocFind
  when the server serves it, as accent serve on a site does.
