The security validator is automatically integrated into the AIDevTeam
orchestrator. All AI-generated tool calls are validated before execution.

Integration Points:

1. Tool Call Parsing:
   - AI responses are parsed for tool calls
   - Each tool call is validated before execution
   - Blocked calls are logged and rejected

2. Automatic Protection:
   ```python
   from elgringo import AIDevTeam

   team = AIDevTeam()

   # This is safe - security validator approves
   result = await team.ask("Show me the git status")

   # This would be blocked automatically
   # The AI cannot execute: rm -rf / or similar
   ```

3. Custom Security Policies:
   ```python
   from elgringo.core.security import SecurityValidator

   # Create custom validator with stricter rules
   validator = SecurityValidator()

   # Add to whitelist
   validator.ALLOWED_OPERATIONS["custom_tool"] = {"safe_op"}

   # Register with orchestrator
   team = AIDevTeam(security_validator=validator)
   ```

4. Bypass for Trusted Operations:
   ```python
   # For admin/development use only
   result = await team.execute_tool(
       "shell", "run",
       {"command": "npm install"},
       bypass_security=True,  # Requires explicit flag
       audit_reason="Development environment setup"
