agent-platform release v4.69.1

agent-manager.agentChart.semver is >=1.0.0 <1.5.0 (was 1.x) (giantswarm/agent#41; epic giantswarm/giantswarm#37705). Generic agent chart 1.5.0 renders no spec.context.compaction on the AgentTemplate: the kagent line from 1.1.0 refuses the field at admission and the platform Harness carries the compaction there. The kagent 1.0 line this release delivers has no other place for it, so an agent rendered by 1.5.0 on a 1.0 installation would run without context compaction. The cap keeps every installation’s agents on 1.4.x until the meta chart moves to the 1.1 lines, where the range becomes >=1.5.0 <2.0.0 together with kagent.harness.compaction. agent-manager composes the range into every agent namespace’s OCIRepository, so the agents’ releases stay where they are and nothing rolls.
