     This function handles the following cases:
     1. If `data` is not a string, it returns the input as-is.
-    2. If `data` is a string and matches common boolean values ("true" or "false"),
-    it returns the corresponding boolean value (True or False).
     3. If `data` is a JSON-encoded string, it attempts to deserialize it using `json.loads()`.
     4. If `data` is a string but cannot be decoded as JSON, it returns the original string.
