Description

Adds the zafnz/devcontainer-features collection. It holds one Feature, jqweb, which installs jqweb, a tool that turns a JSON document into an interactive webpage with text search and jq-style queries. The Feature is published at ghcr.io/zafnz/devcontainer-features/jqweb and pulls without authentication.

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.
