+/**
+ * Normalizes a Cucumber-js format string.
+ *
+ * This function handles structured inputs in the format `key:value`, `"key:value"`,
+ * or `"key":"value"` and returns a normalized string in the form `"key":"value"`.
+ * For simple inputs (e.g., `usage`) or unstructured formats, the function returns the
+ * input unchanged.
+ *
+ * If the input starts with `file://`, an error is thrown to indicate an invalid format.
+ *
+ * @param {string} format - The input format string. Examples include:
+ *                          - `"key:value"`
+ *                          - `"key":"value"`
+ *                          - `key:value`
+ *                          - `usage`
+ *                          - `"file://implementation":"output_file"`
+ * @param {string} assetDir - The directory to prepend to the value for relative paths.
+ * @returns {string} The normalized format string.
+ *
+ * Examples:
+ * - Input: `"html:formatter/report.html"`, `"/project/assets"`
+ *   Output: `"html":"/project/assets/formatter/report.html"`
+ * - Input: `"usage"`, `"/project/assets"`
+ *   Output: `"usage"`
+ * - Input: `"file://implementation":"output_file"`, `"/project/assets"`
+ *   Output: `"file://implementation":"output_file"` (unchanged)
