Rewrite Ralph loop recipes: split into simple vs ideal versions

Align all 4 language recipes (Node.js, Python, .NET, Go) with the
Ralph Playbook architecture:

- Simple version: minimal outer loop with fresh session per iteration
- Ideal version: planning/building modes, backpressure, git integration
- Fresh context isolation instead of in-session context accumulation
- Disk-based shared state via IMPLEMENTATION_PLAN.md
- Example prompt templates (PROMPT_plan.md, PROMPT_build.md, AGENTS.md)
- Updated cookbook README descriptions
