fix: comprehensive test suite enhancements and JSON parsing fixes

- Fix JSON parsing issue in agent_config handling with proper merge strategy
- Add comprehensive test cases matching CDES-203 requirements:
  * Test Case 1: Basic Usage - No Autonomous Use of Q
  * Test Case 2: Autonomous Usage - Autonomous Use of Q
  * Test Case 3: Extended Configuration - Parameter Validation
- Remove undeclared 'folder' variable from terraform tests
- Add agent name extraction validation tests
- Add JSON encoding validation for system prompts with newlines
- Ensure consistent object structures between template and custom configs
- All 13 Terraform tests and 19 TypeScript tests now pass successfully
- Terraform fmt applied for proper code formatting

This addresses all test requirements from the README and CDES-203 ticket.
