test(cli): add coverage for autonomous mode functionality

Add tests for new autonomous mode features:
- Extension host autonomous initialization and environment setup
- Autonomous mode settings validation (orchestrator mode, auto-approval)
- Root task tracking accessors (getLastTaskResult, getRootTaskId)
- ROO_CLI_AUTONOMOUS environment variable management
- Cancel task method

These tests increase patch coverage for the autonomous CLI changes
to meet the 80% codecov threshold.
