v5.1.0

The language server catches up with the language. Everything the compiler
knows — every declaration, every built-in type's methods, every keyword in
every place — the editor now completes, explains, finds and renames, and
it gains formatting, references, signature help, folding, inlay types and
semantic highlighting. What it offers is read from tables the compiler
publishes, each held by a test to the code that reads it, so the editor
cannot fall behind the compiler again.

The editor

• Markdown pages are checked as you type, and a finding is checked
  again when a file it depends on changes: a translation, a .env, a
  project script, a file in public/.
• Go to definition, find references, highlight and rename work for
  every declaration — a type, an enum and its cases, a record's field, a
  const, a data file, an animation, a service's endpoint, a route
  parameter, a socket, a form or element handle — and inside a string's
  {…} splices.
• Completion knows the fields of a record and the methods of each
  built-in type (due. offers plus, isBefore, …), a service's
  endpoints, the keywords each place allows (a store's, an action's, a
  test's steps), type names after :, duration units after a number,
  validate rules, persist settings, format styles, responsive steps,
  Host tags, key names in on key("…"), translation keys in t("…"),
  public env. names, and codes in // wf-allow(.
• Hover says what every name is: Host and the props every element
  takes, a function the language gives, every keyword, a record's field, an
  endpoint, a case, an image's size.
• New: formatting (wf fmt on the open file), find references,
  document highlights, signature help inside a call, folding, inlay hints
  for the type of a state or derived value written without one, and
  semantic highlighting — a name coloured by what it resolves to.

The compiler

• V10: a Host(tag: …) it does not make used to be a div without a
  word; it is now a warning naming the tags it makes.
• An image is typed: hero.widht is a T05, with the fields an
  image has.
