Merge branch 'stack/agent-profiles-1-seam' into stack/agent-profiles-3-wire

master extracted this layer's inline cold-resume resolver into
@deepseek-ai/dsh-api-remotes, whose `setup` was a fixed AgentSetup. A resumed
session composes the preset ITS header recorded, so the option becomes a
function of that header; the resolver builds the setup before the published
re-checks so those stay adjacent to `resume`.
