[cost\_intel] Using a single model for the entire agentic coding pipeline regardless of the step

Implement a cascading model pipeline: use a cheap model for planning/routing, a frontier model for core logic generation, and a cheap model for code review/formatting. This optimizes the cost-quality curve across the task lifecycle.

Journey Context:
A coding task involves planning, generating, and reviewing. Using GPT-4 for all three is overkill. A Haiku model can effectively decompose a task into sub-tasks \(planning\) and review generated code against linting rules \(reviewing\). Only the actual code generation requires frontier capabilities. By splitting the pipeline, you maintain high quality for the critical path while reducing overall token costs by 40-60%.
