Add comprehensive unit tests for sqlite-serve module
Test Suite: 19 tests covering all core functionality Configuration Tests: - test_module_config_default: Verify default initialization - test_module_config_merge: Test config inheritance - test_module_config_merge_preserves_existing: Ensure existing values not overwritten - test_main_config_default: Global config initialization - test_main_config_merge: Global config inheritance Query Execution Tests: - test_execute_query_empty_db: Error handling for missing database - test_execute_query_with_memory_db: Basic SELECT query - test_execute_query_with_positional_params: Positional ? parameters - test_execute_query_with_named_params: Named :name parameters - test_execute_query_multiple_named_params: Multiple named params (order-independent) - test_execute_query_with_like_operator: LIKE operator with parameters - test_execute_query_empty_results: Query returning no rows - test_execute_query_data_types: All SQLite types (INTEGER, TEXT, REAL, BLOB, NULL) Template System Tests: - test_load_templates_from_nonexistent_dir: Graceful handling of missing directories - test_load_templates_from_dir: Auto-discovery of .hbs files - test_template_rendering_with_results: Handlebars rendering with data - test_template_override_behavior: Template re-registration Parameter Handling Tests: - test_named_params_parsing: Parameter syntax parsing logic - test_has_named_params: Detection of named vs positional params Test Coverage: ✓ Configuration management and merging ✓ SQL query execution (positional and named params) ✓ Data type conversion (INTEGER, TEXT, REAL, BLOB, NULL) ✓ Template loading and rendering ✓ Error handling ✓ Edge cases (empty results, missing files, etc.) All tests pass. Module verified working in production.
