Module estimation 

Pluggable cost estimation models.

Four built-in models:

• COCOMO Basic — classic Boehm 1981, three project types
• COCOMO II — modern 2000 calibration, scale factors + cost drivers
• Putnam/SLIM — Rayleigh-curve manpower model
• LOCOMO — LLM Output Cost Model (AI-era code generation cost)
