Subject: [PATCH 1/4] Add Andromeda XXXVI (And XXXVI) dwarf galaxy to
 localGroupSatellites.xml

Adds the newly discovered Local Group dwarf galaxy Andromeda XXXVI from
arXiv:2603.28492. Includes structural parameters (r_h, ellipticity,
position angle), photometry (M_V, M_g, M_r), distance (776 kpc,
DM=24.45), and derived Cartesian/distance fields.
