fix(langgraph-python-threads): pin to stable @copilotkit/* 1.57.0 and intelligence 0.1.0

Replaces canary @copilotkit/* (1.56.5-canary.1777671752) and the intelligence
composite RC tag (0.1.0-rc.16) with the just-released stable artifacts so users
cloning this starter get a reproducible configuration. Also aligns the
Dockerfile copilotkit Python pin (0.1.78) with apps/agent/pyproject.toml (0.1.86).
