Summary

Adds optional YouTube video walkthroughs to the Copilot CLI, GitHub Copilot app, and VS Code Foundry overview pages, alongside the existing written modules. The walkthroughs are mirrored in all five localized versions, and AUTHORING.md documents how to add future tutorial videos accessibly.

Type of change

• Workshop content (lesson Markdown, images)
• Site shell (website/ Astro + Starlight wrapper)
• Copilot configuration (.github/copilot-instructions.md, instructions, agents, skills)
• Repo housekeeping (CI, dependabot, README, license)
• Other: Authoring guidance for tutorial videos

Verification

• Type checks and a clean site build pass.
• Affected pages and translations match their source and intended routes.
• Offline internal link checks pass.
• Changed external links have been checked separately. YouTube was unreachable from the validation environment, so a reviewer should confirm the three videos play, allow embedding, and have accurate captions.

Validation evidence:

• bash .github/skills/build-and-verify-docs/scripts/verify.sh — passed: Astro check reported 0 errors and 0 warnings, the site built 596 pages, and Lychee reported 0 errors.
• Embed audit across all 18 English and localized overview pages — passed: each page has one correctly matched video ID, privacy-enhanced embed URL, and YouTube fallback link, with no autoplay.
• Playwright render check — passed: the English pages render the 16:9 embed without horizontal overflow at 390 px and 1440 px widths; representative es-es, ja-jp, ko-kr, pt-br, and zh-cn pages render the localized headings, introductions, and iframe titles.

Notes for reviewers

• Videos are optional companions; the written modules remain the complete instructions.
• Embeds use youtube-nocookie.com, lazy loading, no autoplay, and a descriptive iframe title. A visible YouTube link remains available because embedded players do not render on github.com.
• Localization follow-up corrected Korean formal register and particles, Japanese and Chinese spacing, localized GitHub Copilot app naming, and Portuguese article usage.

Three Korean READMEs use 따라 해 보세요, which conflicts with the required formal 합니다체 register and should be replaced with 따라 진행합니다.

🔵 Needs a closer look

All three YouTube videos require human verification of playback, embedding permissions, and caption accuracy, which source inspection and render checks cannot establish.

@GeekTrainer I made some video tutorials for the Foundry extensions and this PR embeds them in the Overview page. Do you mind reviewing and merging if ok?
