Slack Notifications 
Tasks that post Slack notifications through incoming webhooks or execution templates.
Use an incoming webhook url (https://hooks.slack.com/...) with either messageText or JSON payload; SlackExecution also needs an executionId to render the built-in status template. Ideal for alerting flows or any external webhook endpoint that accepts Slack-compatible payloads.
