agent-platform release v4.105.0

Changed

• The agentgateway line at 2.2.1 for the controller and the data planes, in both charts (giantswarm/agent-platform#645). 2.2.0 re-pins the line onto upstream main @ 3528a428 with the carried patches replayed; 2.2.1 adds the Substrate resume refusal. The four tags (agentgateway.controller.image.tag and agentgateway.proxy.image.tag of the meta and the connectivity chart) move as one: agentgateway.controller.image names its registry, so Renovate’s helm-values manager finds the controller as it finds the data plane, renovate-custom.json5 groups both images into one agentgateway line PR, and verify-model-catalog holds all four tags equal. The built-in model catalog of 2.2.1 prices Claude Opus 5.5, so the llmRouting.modelCatalog overlay drops its entry; Claude Sonnet 5.5 stays.
