Slack integration for new posts and updates

Post new feedback and changelog updates to a configurable Slack channel, and include quick action buttons (e.g., “Add vote”, “Open in Sleekplan”). Request: Add a Slack app/integration where workspace admins can select which board events (new post, status change, new comment, changelog published) are posted to a channel. Include optional interactive buttons that link back to the post or allow lightweight actions. Benefit: Faster team awareness and reduced context switching — product managers and engineers see new reports immediately in Slack and can act or triage quickly.
