agentName property
The agent these tasks are aimed at, e.g. card_agent /
pkm_agent. Drives routing to the right AgentHarnessFactory and
is the natural unit for filtering across multi-suite runs.
In rare "cross-agent pipeline" suites where different tasks would
hit different agents, leave this as the pipeline name (e.g.
card_to_pkm_pipeline) and let your harness factory dispatch
internally based on task.metadata.
Implementation
final String agentName;
