simtools-derive-telescope-sphere-radius

Derive telescope_sphere_radius from the primary reflector and, where present, the secondary reflector. The command writes telescope_sphere_radius.json in metres and a companion .meta.yml file. The CORSIKA entrance sphere encloses the mirror surfaces, including panel corners and dish curvature, for zenith angles 0-90 degrees with no added margin. The camera is downstream of the reflectors and is outside this entrance sphere. Missing or invalid mirror geometry stops the derivation.

Derive the CORSIKA fiducial sphere radius from telescope model geometry.
