Build the Apple Container extension
Turns the empty scaffold into a working Nova extension for Apple Container and container-compose, in the shape of the Docker Suite extension. Sidebar (Scripts/Sidebar): - System, Containers, Images, Volumes and Networks sections - Containers grouped into compose projects via the com.docker.compose.project label container-compose stamps; project rows drive compose up/down/build against the matching workspace file - Lifecycle, shell, logs, inspect, browse and copy commands per resource - Apple Container publishes no event stream, so the sidebar polls while visible and only reloads a section when a fingerprint of its data changes, which keeps selection and expansion intact Hostnames (Scripts/Hostnames.js): - A container's hostname is <name>.<domain> and the domain lives in Apple Container's config.toml, which has no CLI setter, so the Hostname Domain preference reads and writes that file directly - Changing it offers to register the domain with macOS and restart the services; the write preserves the file's other tables and its mode Language support: - Dockerfile and Compose syntaxes backed by tree-sitter grammars built by Tools/build-syntaxes.sh, pinned to revisions that generate ABI 14 - The Compose syntax is named dockercompose because that is the languageId docker-language-server recognises compose files by - docker-language-server is downloaded on first use rather than bundled, at roughly 40 MB Icons are generated by Tools/make-icons.py so they can be regenerated rather than hand-maintained.
