Subject: [PATCH 04/19] fix: improve Rack 2.1.0 compatibility and RSpec 3.13
 support

- Filter HTTP_VERSION header in env_to_headers (Rack 2.1.0 compatibility)
- Add proper response body encoding handling for ASCII-8BIT content
- Fix ApiFormatter event registration and notification handling
- Update pending test to work with RSpec 3.13 behavior
- Remove Sinatra dependency from test files (incompatible with Rack 2.1.0)

Subject: [PATCH 08/19] fix: prevent RSpec 3.5+ from auto-discovering test
 example groups

Use anonymous classes instead of RSpec::Core::ExampleGroup.describe()
to create example groups for formatter testing. This prevents RSpec 3.5+
from automatically registering and executing these test groups, which
was causing false test failures.

Subject: [PATCH 13/19] fix: remove humanized descriptions from API Blueprint
 output

When parameters or attributes are defined without explicit descriptions,
the DSL auto-generates humanized descriptions (e.g., "option" -> "Option").
This change ensures these auto-generated descriptions are not included
in the API Blueprint output, providing cleaner documentation.

- Added humanize check to description_blank? method
- Updated RSpec tests to expect nil for auto-generated descriptions
- Fixes failing cucumber test for API Blueprint documentation

- Fix parameter description formatting (capitalize "Two level arr")
- Update JSON formatting to match pretty_generate output

The test now expects the actual response examples that are generated
when the PUT endpoint returns the request body.
