remote attach doesn't

Type: Bug

this used to work.

windows host, wsl2 guest, trying to attach to remote machine.

{
			"name": "attach",
			"type": "cppdbg",
			"request": "attach",
			"program": "/home/user/program",
			"processId": "${command:pickRemoteProcess}",
			"pipeTransport": {
				"pipeProgram": "/usr/bin/ssh",
				"pipeArgs": [
					"-o LogLevel=error",
					"user@remote-host"
				]
			},
			"logging": {
				"engineLogging": true
			}
}

the debug panel just shows the spinner. debug console shows NO output. stopping/starting has no effect. neither does reloading window.

ps -ax on the wsl2 guest shows a bunch of these:

23875 pts/0    S+     0:00 /usr/bin/ssh user@remote-host sh -c "uname && if [ $(uname) = \"Linux\" ] ; then ps axww -o pid=,comm=aaaaaaaaaaaaaaaaaaaa
23877 pts/0    S+     0:00 /usr/bin/ssh user@remote-host sh -c "uname && if [ $(uname) = \"Linux\" ] ; then ps axww -o pid=,comm=aaaaaaaaaaaaaaaaaaaa
...

htop on the remote machine (remote-host) shows those processes running:

 8995 root       20   0  153M  5176  3892 S  0.0  0.1  0:00.00 │  ├─ sshd: user [priv]
 8996 sshd       20   0  114M  2880  1752 S  0.0  0.1  0:00.00 │  │  └─ sshd: user [net]
 8835 root       20   0  153M  5172  3892 S  0.0  0.1  0:00.01 │  ├─ sshd: user [priv]
 8836 sshd       20   0  114M  2880  1752 S  0.0  0.1  0:00.00 │  │  └─ sshd: user [net]

running the /usr/bin/ssh ... command manually on the wsl2 guest shows the expected remote process listing.

未指定源文件或测试。先使用 cppdbg 和 pipeTransport 重现 WSL2-to-remote attach 配置，然后跟踪远程进程选择和 attach 流程；当 spinner 结束且调试器完成 attach 或报告明确错误时，即表示完成。
