searxng: a search tool — tools-only, a stateless search has nothing to observe.
icecast: status tool, emits stream.started/.stopped by diffing live mountpoints.
photos: status/albums/recent tools, emits item.added (immich-shaped API, coded
defensively since the stub ships a placeholder image — flagged in the code).
Typecheck; manifests parse.
Each module becomes modules/<name>/ holding module.json, with room for
the rest of what a module is — its tools, health checks, provisioning,
lifecycle — which the conversion from hal still has to bring across.
The flat <name>.json was only the resource-declaration half.
