v0.1.49: Fix _read_pid test failures after socket connectivity check

What's New

• CI test fix: two _read_pid tests were failing after the v0.1.48 socket connectivity check. Tests now bind a real Unix socket and patch get_socket_path so the check passes correctly. No behavior changes to the library itself.

Details

• tests/test_daemon_server.py: test_read_pid_alive_process binds real Unix socket for connectivity check
• tests/test_daemon_server_coverage.py: test_read_pid_valid same fix
