Apply host-provided safe area insets as padding on main containers
across all examples. This ensures content doesn't render under
system UI elements like phone notches.
React apps use `useState` + `onhostcontextchanged` handler with
initial fetch via `getHostContext()` in `useEffect`. Vanilla JS
apps apply padding in the handler and invoke it after `connect()`.

* feat: add server helpers and optional connect() transport
Add `src/server/` with convenience functions for registering MCP App tools
and resources:
- `registerAppTool(server, name, config, handler)`
- `registerAppResource(server, name, uri, config, callback)`
The `transport` parameter in `App.connect()` is now optional, defaulting to
`PostMessageTransport(window.parent)`.
