Templates and car surfaces

The full reference lives in [`docs/templates.md`](../../docs/templates.md).

Read that file now, in full, before adding or changing a template. This skill deliberately does not restate it.

The traps it covers, so you know what you're looking for:

1. Native template objects are module-level singletons, not per instance. A JS

Template is a thin proxy holding an id; every call is HybridXTemplate.method(this.id, …). The id is the only correlation key. There is no dispose API, and calling into a popped template rejects with templateNotFound.

1. `MapTemplate` has a hard-coded `id = 'AutoPlayRoot'` and is effectively a singleton —

any id you pass is silently discarded. Don't construct two.

1. `MessageTemplate` does not extend `Template` and has only push().
2. Action and `HeaderActions` configs pick exactly one platform branch at runtime.

Filling only ios or only android yields no buttons on the other platform, silently.

1. Several methods no-op or behave differently per platform (setManeuverState,

updateManeuvers, SignInTemplate on iOS), and CarPlay will not repaint maneuver colors in place — a theme switch needs a resend with a new id.

1. useMapTemplate() / useSafeAreaInsets() / useFocusedEffect() only work inside a

component rendered on a car surface: a MapTemplate's component, a cluster, or the dashboard. Nowhere else.

Then follow the file, not this summary.
