Add model customization to all subagents (#7)

Implements claude-code v1.0.64's model customization feature by adding
model specifications to all 46 subagents based on task complexity:

- Claude Haiku 3.5 (8 agents): Simple tasks like data analysis, documentation
- Claude Sonnet 4 (26 agents): Development, engineering, and standard tasks
- Claude Opus 4 (11 agents): Complex tasks requiring maximum capability

This task-based model tiering ensures cost-effective AI usage while
maintaining quality for complex tasks.

Updates:
- Added model field to YAML frontmatter for all agent files
- Updated README with comprehensive model assignments
- Added model configuration documentation

+### Model Configuration
+
+As of Claude Code v1.0.64, subagents can specify which Claude model they should use. This allows for cost-effective task delegation based on complexity:
+
+- **Low Complexity (Haiku 3.5)**: Simple tasks like basic data analysis, documentation generation, and standard responses
+- **Medium Complexity (Sonnet 4)**: Development tasks, code review, testing, and standard engineering work  
+- **High Complexity (Opus 4)**: Critical tasks like security auditing, architecture review, incident response, and AI/ML engineering
+
+Available models:
+- `claude-3-5-haiku-20241022` - Fast and cost-effective for simple tasks
+- `claude-sonnet-4-20250514` - Balanced performance for most development work
+- `claude-opus-4-20250514` - Most capable for complex analysis and critical tasks
+
+If no model is specified, the subagent will use the system's default model.

 ## Agent Orchestration Patterns
 
 Claude Code automatically coordinates agents using these common patterns:
