Notify Slack about new GitLab merge requests

Notify a Slack channel when a new GitLab merge request is opened. Help reviewers notice incoming work with the title, merge request number, project, author, branches and source link. Connect GitLab and Slack, choose the source project using the standard resource browser and select a Slack channel where FastHook can post. The Actions filter is prefilled with open; edits, approvals, merges and closures do not post another creation alert. Wait for the Trigger to show Connected after activation before opening a test merge request. Only new webhook events are processed, not existing merge requests. The fictional example contains German characters. Messages use plain text with link previews disabled. Descriptions, code and attachments are not copied. This is a one-way notification, not a review-status sync. Project members still need GitLab access to open the source link; title and branch names become visible to channel members. Manual reruns can send another message.
