Major Changes

• c1efc1d: Flatten spec.

  The updated folder-based spec does not work well when used.
  It creates conflicting schema names between code/* and status/*.

  Also, the naming scheme of error~any-of and error=aborted create invalid key per OpenAPI spec.

  They are now replaced with -.
  Although it missed some meaning, that's a compromise need to be made.
