feat(errors): add ignore_tool_parameter_parse_errors

[manucorporat]

…ageStream to handle parse errors

• Introduced UnableToParseToolParameterError for better error handling.
• Updated BetaMessageStream to conditionally ignore tool parameter parse errors based on new ignore_tool_parameter_parse_errors flag in MessageCreateParamsBase.
• Enhanced error handling during JSON parsing in BetaMessageStream.

I don't think we should ship a ignore_tool_parameter_parse_errors parameter.

Instead it would be a much better API if the error callback handler could somehow tell the stream to keep going.

e.g. something like this

stream.on('error', (error) => {
  if (error instanceof UnableToParseToolParameterError) {
    return { continue: true };
  }
});

The separate UnableToParseToolParameterError error class is a good change 👍.
