Use client connection for GET requests

[tagliala]

Ensure the configured client options (SSL, proxy, timeouts) are honored
by performing GETs via the client connection when fetching the OpenID
configuration and the JWKS certificates. Previously these requests used
Faraday.get, bypassing the client’s settings.

Additionally, add byebug for debugging, bump RuboCop and related cops,
update the RuboCop todo, and ignore .byebug_history.

The byebug gem should be placed in a development/test group rather than at the top level. This ensures it's only loaded in development and test environments, not in production. Consider wrapping it in a group block:

group :development, :test do
  gem 'byebug'
end

Suggested change

	gem 'byebug'
	gem 'rake'
	gem 'rake'
	group :development, :test do
	gem 'byebug'
	end

@copilot in this case, when there is a .gemspec, the Gemfile is for development and test
