Read runtime context

const context = await host.getContext();

The returned AppHostContext contains:

Field	Meaning
protocolVersion	Host protocol version; currently 1
installationId	Current account-scoped app installation
appKey, appVersion	Installed app identity
surfaceKey	Frontend Page surface currently open
locale, timezone	Organization/user rendering context
capabilities	Available semantic operations
bindings.dataWorkspaces	Resolved Data Workspace binding aliases

if (context.capabilities.includes('workflow.run')) {
  enableGenerateButton();
}

document.documentElement.dataset.theme = context.theme.colorScheme;

Bindings contain only IDs explicitly mapped by the Frontend Page resource. Do not cache them across installations.
