Description

Adds the nabil-becker/devcontainer-features collection to the index. It currently publishes three Features to ghcr.io/nabil-becker/devcontainer-features:

• go-task - Task from GitHub releases, verified against the release's task_checksums.txt, with bash/zsh completions.
• devcontainer-cli - @devcontainers/cli on a private, sha256-verified Node.js under /opt/devcontainer-cli, so devcontainer works inside a container without a system-wide Node.js on PATH.
• claude-code - the Claude Code CLI as its native release binary (no Node.js), checksum-verified against the release manifest, version pinnable, auto-updater disabled.

Each Feature follows the feature-starter layout with test/<id> scenarios run in CI on Debian and Ubuntu, and is released via devcontainers/action. The repository is public with contributing, security and code-of-conduct policies, DCO sign-off, and a protected default branch.

Collection checklist

• Collection name
• Maintainer name
• Maintainer contact link (i.e. link to a GitHub repo, email)
• Repository URL
• OCI Reference (must be the collection root, e.g. ghcr.io/<owner>/<repo> — one entry per repository, not one per Feature; do not include http:// or https://)
• I acknowledge that this collection provides new functionality, distinct from the existing collections part of this index.
