fix: defer Copilot CLI resolution until agent nodes exist

CopilotAgentBundle.CreateAsync unconditionally resolved the Copilot CLI
path and started a CopilotClient, even for workflows with no agent
nodes (e.g. request-port-only workflows). This caused a hard failure
in CI where the copilot binary is not on PATH.

Move CLI path resolution, client creation, and agent setup inside a
guard that checks whether the workflow actually contains agent nodes.
