Clean up stale/unnecessary files from PeasyAI

Delete:
- Config (Amazon Brazil build config, not relevant to open-source)
- cursor-mcp-settings.example.json, mcp-config.json (superseded by peasyai-mcp CLI)
- env.template (deprecated in favor of ~/.peasyai/settings.json)
- analyze-checker-errors.py, analyze-errors.py, compute_metrics.py,
  visualize-pk-vs-tokens.py (one-off analysis scripts at project root)
- resources/pipeline.json (old pipeline config, unused)
- src/resources/p_syntax_rules.txt (unused duplicate)
- src/rag/ (old faiss-based RAG scripts, replaced by src/core/rag/)

Move:
- evaluate_peasyai.py → scripts/evaluate_peasyai.py

Update .gitignore:
- Add generated_projects/, .peasyai_workflows.json
- Remove stale cursor-mcp-settings.json entry
