A todo node's key and text were hand-expanded `{field}` strings. They are now Jinja templates rendered through the new hive-template crate (minijinja, an unknown variable is an error), and the controller's save check reads the variables the template uses. The flows document is version 2; a version 1 document reads as version 2 with each `{field}` converted to `{{ field }}`, and the next save writes it.

hive-template
The one template language the hyperhive workspace renders with: Jinja, through
minijinja. A value is {{ name }}, a
block is {% if cond %}...{% endif %}, and a lone { or } stays plain text.
render(template, &context): the text, or a message when the template does not parse or names a variable the context lacks. An unknown variable is an error, never an empty string.variables(template): the variables the template reads, so a caller can refuse an unknown field when the template is saved instead of when it renders.
Used by the notification router's flow templates (swarm-notify-router,
swarm-wire).
