agent-platform release v4.135.0

components.agent-manager.versionRange is >=2.1.0 <3.0.0 (was >=1.13.0 <2.0.0), the connectivity release’s agent-manager migrate run takes agent-manager 2.1.0, and the customer BOM pins it. get_session answers a bounded summary by default (detail: full for every task) beside the new get_session_turn and delete_session (giantswarm/agent-manager#150, #155); get_info lists in namespaces.managed only the namespaces where the caller may create agents (giantswarm/agent-manager#71); an agent on a claude Harness without a harness.egress entry is refused, naming the entry (giantswarm/agent-manager#148). The tenant reconciler ships off (agent-manager.tenants.enabled). Supersedes giantswarm/agent-platform#1001.
