Rolemodel::ResourceFor::ControllerExtension

[OutlawAndy]

Adds Rolemodel::ResourceFor::ControllerExtension, a small utility intended to simplify “child resources with many possible parents” by deriving the parent model and id param from route defaults (via routing concerns), and making the helper available across controllers through the engine.

Pattern extracted from TarscoBoltedTank

What Changed?

• Introduces resource_for as a private controller method via a new ControllerExtension concern.
• Hooks the concern into ActionController::Base via a Rails engine initializer.
• Adds request-level spec coverage and a README section documenting routing + controller usage and security considerations.
