v0.1.0

Added

• The example integration, example, and its program, acme-example, built from
  cmd/acme-example/. acme-example describe prints the integration's description,
  contracts/integration/v1 of qoryai/integrations, with the program's version filled in;
  it serves every domain, since it has no domains. acme-example credential --settings <json> -- <project> plays the gateway's credential adapter: it reads a static API token
  from token_file, a file only its owner reads, and answers with the token applied to
  api.example.com, bearer, on /v1/projects/<project> and what is under it, and the
  placeholder EXAMPLE_TOKEN. The secret token is refused on a command line, and
  reported by name, never by value. Settings with neither token nor token_file are
  refused with a message that says to set token_file. A token file that grants group or
  others any permission is refused with a message that says so and to make it 0600.
• The tests, which hand what the program prints to the conformance package of
  github.com/qoryai/integrations v0.3.0: the description,
  the answer, and each failure.
• ci.yml and release.yml, which call the workflows of qoryai/integrations: ci.yml
  its go.yml at @v0.3.0, the checks on every push to
  main and next and on every pull request, where a pull request from this repository's
  next counts the push run on its commit; and release.yml its release.yml at
  @v0.3.0, on a tag vX.Y.Z a release by the rule
  every integration's releases follow.
• The README, the guide from renaming the template to listing the integration in the
  catalog.
• The licence, MIT No Attribution (MIT-0): an integration started from the template
  owes it no notice and no credit, and is licensed as its author chooses.
