This plugin implements ProviderRegistration directly. It demonstrates connection negotiation,
catalog and session listing, session creation, prompt and command disposition, settings,
persistence and replay, archive actions, and an ordinary child session.
The provider emits versioned provider-result timeline items for its root and child sessions.
index.client.tsx registers the Zod schema and React Native renderer for those items. The server
and client share only the item kind and schema under shared/.
The provider receives Paseo host tools through config.mcpServers; it does not receive a second
callback tool API.
