fix: improve PHP 8.4 stream timeout handling (issue #131)

[sonarta]

Problem

Users report StreamException: Stream timed out error when using PHP 8.4, particularly when retrieving large amounts of data.

Solution

• Replace socket_get_status() with stream_get_meta_data() for clarity
• Only throw timeout exception when timed_out=true AND no data received
• Add configurable throw_timeout_exception option

Testing

Tested on PHP 8.4.15 with RouterOS 7.12.1:

• ✅ 12 stress tests passed
• ✅ 72,788 total records retrieved
• ✅ Zero stream timeout errors

Usage

If issues persist, disable timeout exception:

$client = new Client([
    'throw_timeout_exception' => false,
]);

Fixes #131
