Bevy project templates (docs-first stub)

Not a full port. Docs-first stub. Godot counterpart: godot-project-templates.

When to use

Load this when choosing a starting Cargo feature set. App construction details stay on bevy-project-foundations. This file does not ship a template repository.

ECS shape

• Profiles opened on the crate page: default (2d, 3d, ui, audio), 2d, 3d, ui. Example snippet shows default-features = false plus a profile feature. The sample version string on that page said 0.18; the pin on bevy-master stays 0.20.0.
• Minimal app: the crate docs show App::new().add_systems(Update, ...).run().
• Windowed games: DefaultPlugins remains the plugin set named on the plugins page.
• No repo: do not invent a template URL.
