Adds workshop/13-schedule-it.md, the successor to node 12 ("Test and Improve Your Workflow"). This node teaches learners how to add a schedule (cron) trigger to their workflow YAML so their daily status report runs automatically every morning — no manual intervention needed. It covers cron syntax, UTC timing considerations, a reference table of common cadences, and how to verify the schedule is registered in the GitHub Actions UI. Also updates workshop/README.md to mark node 13 as complete in the curriculum table.

@copilot do not use cron, use fuzzy syntax from gh-aw

Done. Replaced all cron expressions with gh-aw fuzzy schedule syntax (schedule: daily, schedule: daily on weekdays, schedule: weekly, etc.). The node now explains that gh aw compile expands these natural-language expressions into cron automatically — learners never need to write raw cron. Commit: Replace cron syntax with gh-aw fuzzy schedule syntax in node 13.
