Changelog

Unreleased

Right-click menus: Archify commands (Archify | New Diagram…, Open Preview, Render to HTML File…, Open in Archify HTML Viewer) now sit in their own section at the bottom of the Explorer and editor-tab menus, instead of between New File, New Folder and the other built-in entries.
The new-diagram command is renamed Archify | New Diagram… (was New Diagram Archify…).

Clearer descriptions: the Marketplace description, README and messages now say plainly that diagrams are .archify files in YAML. Archify's own JSON files (*.architecture.json, …) and rendered HTML are described as also supported, in their own section.
The rendered-HTML editor is now called Archify HTML Viewer (was Archify Diagram Viewer, the same name as the extension), and its command Open in Archify HTML Viewer.
Messages: "open a .archify diagram first"; an empty or broken .archify file asks for valid YAML, not JSON.

Brand completion: after brand: in .archify files and Archify JSON sources, the editor suggests the 107 built-in brand IDs with their product names. Aliases and product names match too (kafka → apache-kafka, postgres → postgresql).
Unknown brands are underlined on their own line. Archify reports these without a location, so they used to appear at the top of the file.

The new-diagram command is now titled New Diagram Archify… everywhere, including the Explorer folder menu, where it read New Diagram….

New Diagram… (Explorer folder menu, File → New File…, Command Palette): pick Architecture, Workflow, Sequence, Data Flow, Lifecycle or Everyday Plan, enter a name, and a small valid .archify (YAML) file is created from a template and opened as a diagram. Title and output file follow the name.

.archify files are YAML. They are parsed as YAML and handed to the renderer as JSON. Older JSON .archify files still open, since JSON is valid YAML.
Clicking a .archify file opens the diagram: the new Archify Diagram editor is the default for *.archify. Show Source opens the YAML beside it, and the diagram follows your edits.
YAML syntax errors are reported in the Problems panel. Archify validation problems point at the matching YAML line.
Schema completion for .archify works through the YAML extension (redhat.vscode-yaml), via yamlValidation.

.archify files: Archify JSON diagram sources with their own extension. They open as JSON, preview with the same button and keys, report problems, and get completion from the schema of their diagram_type.
Render to HTML and Open in Browser name the output after the diagram (web.archify → web.html).
