Model Configuration Support for Sub Agents

Feature Request
Model Field for Claude Code Sub Agents

Could you add a model field to sub agent frontmatter configuration? This would allow specifying different Claude models for different agent use cases - e.g., using Opus 4 for complex coding agents and Sonnet 4 for code review agents. This would optimize both performance and cost based on task complexity.

Current frontmatter format:

---
name: agent-name
description: Agent purpose
tools: tool1, tool2
---

Requested addition:

---
name: agent-name
description: Agent purpose  
tools: tool1, tool2
model: opus  # or sonnet
---

This would enable cost optimization by using the appropriate model tier for each agent's complexity level.
