[github-actions]

What Changed Upstream

Between the last sync (SHA 9be2d4470afa3e04ae4bc22611577dd0f34fe518, 2026-03-27) and today, github/copilot-cli-for-beginners received 30 commits. The content-relevant changes were:

• PR #43 — Replace "Copilot coding agent" with "Copilot cloud agent" across 01-setup-and-first-steps, 03-development-workflows, 05-skills, and appendices/ci-cd-integration.md
• PR #24 recovery — Significant content updates to 01-setup-and-first-steps (15 additions / 12 deletions) and 02-context-conversations (16 additions / 7 deletions), including new /new and /rewind commands, updated context token example, expanded command tables, and corrected demo intro text
• Minor README.md and 02-context-conversations wording fixes

The remaining commits were CI automation, traffic data collection, and internal tooling changes — not mirrored to the Learning Hub.
