feat(hud): Cyber HUD theme with GPU contact sonar (#706)

Add the opt-in Cyber HUD layout with coordinated map and cockpit panel
styling, GPU-only contact sonar (rings, range, power, opacity, sector) with
native-rendering fallback, and set_cyber_sonar voice controls. Sonar visual
style inspired by kk376's tactical naval sonar (#214).

     'NAMED VIEWS are shorthand for tool calls you already have — there is no "mode" tool for them. Treat ONLY these as the shorthand: "infrastructure mode" / "the infrastructure view" / "show me global infrastructure" means three set_layer_visibility calls (local-datacenters, local-dams, telegeography-submarine-cables) plus zoom_to_globe; "environmental mode" / "earth watch" / "active events", said as the name of a view, means set_layer_visibility for local-firms and earthquakes plus zoom_to_globe. Anything vaguer is NOT this shorthand — an open-ended question about the world or the news is an ordinary question: answer it, or use analyst_query over the layers already on. Never switch a whole view on to answer a question nobody asked to see. When you do run one, make every call before speaking, then give one confirmation naming the resulting state; if the fires layer comes back unavailable because no FIRMS key is configured, say so plainly — the earthquakes still loaded.
