feat: implement OpenClaw agent training system with CLI command execution

Added comprehensive agent training functionality that executes actual AITBC CLI commands:

- Renamed openclaw_operations to openclaw_training_operations in aitbc_cli.py
- Added train action with agent/validate/certify subcommands to openclaw_operations
- Implemented agent training that loads JSON training data and executes real CLI commands
- Added operation mapping for wallet, blockchain, messaging, and system commands
- Skip
