chore: update ESLint configuration and improve TypeScript type handling

- Added additional test file patterns to ESLint configuration for better coverage.
- Introduced new rule to ignore unused TypeScript variables starting with an underscore.
- Updated `PermissionController` to set approval mode correctly.
- Refactored timeout constants in `Query` class for better maintainability.
- Enhanced E2E tests for permission control and multi-turn conversations with clearer prompts and expectations.
- Removed outdated simple query test file and added new single-turn test suite for better organization.
