fix: use Stop hook instead of Notification for plugin compatibility

Plugin hooks.json does not support the Notification event type.
Switch to Stop hook which fires when Claude finishes and waits for
user input — the exact moment a notification is needed.

Also remove extra quotes from command path and drop the now-irrelevant
notification_type filter.
