Note

Low Risk
Scope is limited to dev/suggested dependency version bounds in composer.json; runtime behavior only shifts for environments that install the optional cache middleware, with no SDK code changes in this diff.

Overview
Bumps the dev dependency kevinrob/guzzle-cache-middleware from ^4.0 to ^7.0, and updates the matching suggest note from ^3 to ^7 so optional install guidance stays aligned.

There are no application or test source changes in this PR—only composer.json constraint updates. Consumers who follow the suggest and use the default Guzzle-based feature requester will pull in v7’s caching behavior (e.g. RFC 9111–related Authorization header handling, binary cache fixes, Flysystem v3, dropped doctrine/cache support in the upstream package).
