Preview when users are remote

Craft-style apps write static output (for example dist/) into the session workdir. Digitorn shows that tree in the Preview pane of the UI. Agents can inspect it with the preview module (inspect, snapshot).

There is no tools.modules.web_preview module.

What to put in app YAML​

app.yaml
tools:
  modules:
    filesystem:
      config:
        workspace: "."
    preview: {}
  capabilities:
    grant:
      - module: filesystem
        actions: [read, write, edit, glob, grep]
      - module: preview
        actions: [inspect, snapshot]

ui:
  workspace:
    render_mode: html
    entry_file: dist/index.html
    position: right

Optional: agent-started dev servers​

If an agent starts Vite / Next on a loopback port via bash, that port is not automatically public. Publishing it is infrastructure around Digitorn (reverse proxy / DNS), not an app-YAML feature.
