Add missing stage scripts (0, 8, 9) for complete training

Created placeholder shell scripts for stages that only had JSON definitions:
- stage0_environment_setup.sh - Environment setup and prerequisites
- stage8_advanced_agent_specialization.sh - Bounty systems, portfolio management, knowledge graph marketing
- stage9_multi_chain_architecture.sh - Cross-chain operations and multi-chain deployment

These scripts use the Python-based training setup to execute JSON-defined operations,
allowing the complete training program (stages 0-9) to run without errors.
