[QUICK WIN] Model Cost Router

[EcosystemNetwork]

Route simple tasks to cheaper models automatically.

Acceptance Criteria

• Detect task complexity (token count, tool requirements)
• Route simple queries to cheaper models (gpt-3.5, claude-haiku)
• Route complex tasks to stronger models (gpt-4, claude-opus)
• Configurable cost/quality tradeoff
• Cost savings tracking

Implementation

• Create middleware that intercepts model requests
• Add complexity scoring heuristics
• Implement routing logic with fallback
