Background workflow agent spawns now carry a description and workflow phase

What

When Claude Code spawns a background agent as part of a workflow, the spawn call now includes description (taken from the agent's label) and workflowPhase (taken from the agent's phase). The progress updates sent for workflow agents also now include a promptFramed value.

Why

This gives background workflow agents more context about which workflow and phase they belong to, which should make their progress and purpose easier to track.
