Establish the Koi Swagger parser release

Prepare the OpenAPI parser and Dart generator as a publishable Koi package with CLI entrypoint, docs, examples, tests, and pub.dev release metadata.

Constraint: Initial GitHub import follows koi_blueprint_flutter identity mr.koi <i@mrkoi.is>.

Rejected: Keep local runtime state in the initial repository | .dart_tool, .omx, and pubspec.lock are ignored for a reusable package source tree.

Confidence: high

Scope-risk: moderate

Directive: Keep generated-output behavior covered by parser and generator tests before changing rendering rules.

Tested: dart analyze; dart test; PUB_HOSTED_URL=https://pub.dev dart pub publish --dry-run

Not-tested: End-to-end downstream build_runner compilation of generated Retrofit/Freezed output.
