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
