feat: skip SRV lookup for IP addresses and localhost
Performing DNS SRV lookups for hosts that are already direct IP
addresses or special-case hostnames like 'localhost' is
unnecessary.

In addition, several related test suite improvements
have been included:

- A bug in the Bedrock mock packet creation was fixed where the magic
  GUID was being written to an incorrect buffer offset.
- The DNS mocking strategy in the Java tests has been refactored for
  better accuracy by mocking the `dns.promises.Resolver` class.
- An error test for the Bedrock pinger was corrected to properly
  handle a promise rejection instead of a synchronous throw.

feat: implement SRV record lookup and improve ping logic
Add support for DNS SRV record lookups (`_minecraft._tcp`) to
automatically resolve the correct server host and port, falling back
to the provided address if no record is found. This makes server
discovery compliant with standard Minecraft client behavior.

The Java ping implementation has been refactored:
- The `varint` module is rewritten to throw specific error codes and
  its `decodeVarInt` function now returns bytes read, which simplifies
  parsing logic.
- The core ping logic is now promise-based and modular, breaking out
  packet creation and response processing into helper functions.
- The TCP stream handler now robustly processes chunked data by
  catching recoverable decoder errors and waiting for more data,
  preventing crashes on incomplete packets.
- Error handling is improved.
