Module observables 

Forward GNSS observable prediction.

This module owns the language-independent geometry behind Sidereon’ Observables.predict: transmit-time iteration, Sagnac rotation, line of sight, range rate, Doppler, and topocentric azimuth/elevation. Ephemeris parsing and interpolation stay with their existing SP3/broadcast products.
