[Feature Request] Desktop mode does not support webhook hooks for notifications

Bug Description
On claude code desktop mode, I want to be able to get notifications on services like slack when it has finished certain tasks etc. This works today in claude code, but not the desktop via this cfg: {
"hooks": {
"Notification": [{
"hooks": [{
"type": "command",
"command": "curl -X POST -H 'Content-type: application/json' --data '{\"text\":\"🔔 Claude needs your input\"}' https://hooks.slack.com/services/YOUR/WEBHOOK/URL"
}]
}],
"Stop": [{
"hooks": [{
"type": "command",
"command": "curl -X POST -H 'Content-type: application/json' --data '{\"text\":\"✅ Claude finished\"}' https://hooks.slack.com/services/YOUR/WEBHOOK/URL"
}]
}]
}
}
