searxng, icecast, photos: full nox modules (ADR 0044/0046)

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.
