Fresh validation against the current PR head (8179bac):

• the PR is scoped to openEBS/Probot copy in src/data/projects.js, plus restoring the final newline
• imported projectList and confirmed the corrected openEBS description, Probot description, and Probot tag
• GITHUB_TOKEN=$(gh auth token) pnpm build -> Astro build succeeded, 2 pages
• generated dist/index.html contains containerized block storage, not containerized block storage
• generated dist/index.html contains building GitHub Apps in Node.js, not building Github Apps in Node.js
• generated dist/index.html contains the GitHub tag
• git diff --check origin/main...HEAD -> clean

Generated .astro/dist output was restored after validation.
