Astro consolidates nova (sky panel) and scope (telescope/eyepiece
catalog) into a single binary with shared config (location, Bortle).
Press 'g' to flip between Sky and Gear modes.

Sky mode is nova's full feature set: weather, ephemeris, visibility
bars, astronomical events, starcharts, APOD, tonight-summary fallback.

Gear mode is scope's full feature set: telescopes + eyepieces catalog,
optics math, tagging, observation logs, CSV/JSON export.

First-run migration copies ~/.nova/config.yml and ~/.scope/data.json
into ~/.astro/ so existing users carry settings forward.
