+- Bisect pass rise/set to ~0.2 s and fit peak elevation with a parabola.
+- Mark passes visible from Earth-shadow and civil-twilight checks.
+- Add `getNextSatellitePass(noradId, options)` for any loaded catalog satellite.
+- `next_iss_pass` retains the next geometric pass and adds visibility metadata. `next_satellite_pass` adds bounded loaded-catalog name/NORAD lookup and optional visible-only filtering (Rehaan Delmotra, #451; maintainer adaptation).
