[Bug] Pulsar client can't have static storage duration

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar-client-cpp/issues) and found nothing similar.

### Version

- pulsar client 2.9.0
- ubuntu linux

### Minimal reproduce step

int main(int argc, char** argv)
{
static ::pulsar::Client client{"pulsar://0.0.0.0:6650"};
// don't call client.close();
return 0;
}

### What did you expect to see?

The program should terminate gracefully, instead it seg faults. If I call client.close(), there is no issue.

### What did you see instead?

The program seg faults with the following trace:

In gdb:
```
Program received signal SIGSEGV, Segmentation fault.

### Anything else?

_No response_

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Start with the minimal static pulsar::Client reproduction on Ubuntu and inspect pulsar::Client::~Client in /usr/include/pulsar/Client.h, then use the supplied gdb backtrace to follow shutdown and shared-pointer destruction. Confirm the failure occurs when static destruction runs without client.close(); done means the program exits gracefully without requiring an explicit close.
