⚙️ Add strategic model assignments to slash commands

Add model specifications to commands for cost-performance optimization:

Haiku (fast & cheap):
- personality-change: Simple config file updates
- load-rules: Pattern-based file loading

Sonnet (cost-conscious for Opus users):
- address-pr-comments: Intelligent triage within clear guidelines
- setup-environment: Environment detection and setup

Opus (deep reasoning):
- create-prompt: Meta-cognitive prompt engineering
- generate-AGENTS-file: Critical project context synthesis

This complements the agent model assignments, creating a complete
cost-performance strategy across the entire AI coding toolkit.
