• Workflow-level status — documented pattern for reporting multi-job workflow status

• Filter unnamed steps — steps without an explicit id (auto-generated hex hashes) are now filtered out (#131)
• Retry on failure — webhook send retries up to 3 times with linear backoff on transient errors (#196)
• Sanitize template data — user-controlled data (commit messages, PR titles) containing Handlebars syntax no longer causes runtime errors (#259)
