fix: Adjust timeout and exception handling for URLDownload compatibility

- Import java.time.Duration for timeout settings
- Use Duration.ofMillis() for setConnectTimeout (URLDownload only supports connect timeout)
- Remove setReadTimeout (not supported by URLDownload class)
- Change catch block to ParseException | FetcherException (IOException not thrown)
- Code now compiles successfully
