agent-platform release v3.23.1

agent-manager.agentChart.semver is >=0.2.1 <1.0.0 (was x.x.x) in both charts. Generic agent chart 1.0.0 (published 2026-09-11) renders the kagent API v2 shape (kagent.dev/v1alpha3 AgentTemplate), which no 3.x installation can install; agent-manager composes this range into the per-namespace agent OCIRepository it writes on every create_agent, and the meta chart’s explicit forward wins over agent-manager 0.4.5’s own bounded default — so an open range here pulled 1.0.0 into every new managed namespace (the ATS round trip on this branch reproduced it: HelmRelease ats-managed-agent InstallFailed no matches for kind AgentTemplate). The three pre-existing per-namespace OCIRepository objects were bounded by hand already; this makes every future one bounded too. Every installation with agent-manager on rolls the agent-manager pod once (--agent-chart-semver changes); nothing else in the render differs. The 4.0 line moves the range to 1.x.
