1.0.0 — one API line, everything the endpoint offers

Eleven releases of finding out what this plugin is for, and the answer settled:
it makes the two things the package keeps in separate files — the docblock
markup and the route map — visible as one endpoint, while you type.

Nothing in the public surface is expected to change now, which is what the
number says. The markup grammar, the inspections and their ids, the settings
keys and the API line are what they will be.

Added

• One API line above each routed method, with everything the endpoint
  offers under it. Its page in the reference documentation, and the endpoint
  itself as a request in each format api:export produces — Bruno, cURL, HTTP
  Client, Postman, Markdown. The gutter icon on the route map's action key opens
  the same list.

  Before this the two halves lived apart: a link that opened documentation, and
  an export buried in the editor's context menu where nobody found it. One
  subject, one place.

Changed

• The line appears when either half is possible, not only both. It used to
  need a documentation address, so a project without APP_URL got no line — and
  with it no export, which never needed an address in the first place. The list
  now holds what is actually available, and an item that is missing is the answer
  to why: a version a module assembles at runtime cannot be addressed, a version
  in hidden_versions is never loaded by the page, a project without artisan
  has nothing to export with.

• The label is API rather than API docs: v1.GET. It sits above every
  routed method in a controller, and forty repetitions of a long label read as
  noise. What it leads to is one click away, and in the tooltip without one.
