…#1706) Retag astronomy citation markers from the Materials namespace into the numbered References scheme: [M22] -> [27] (Meeus), [M23] -> [28] (NASA Planetary Fact Sheet), [M21] -> [4] (JPL DE440/DE441). Add the matching Reference 27 and Reference 28 definition entries and drop the now-orphan Materials 20 (Espenak), 21, 22, 23 definitions. Drop the orphan Materials 6 (Palik) definition. Fix two source nits: G0F and weak mixing angle were tagged [2] (PDG) but are CODATA-derived, so retag to [0]; remove the spurious Materials 5 (Malitson refractive-index) citation from the fused silica density rvSiO2 line, keeping Materials 7.

…1707) Update the Milky Way and Andromeda (M31, NGC 224) constants to current literature values and point them at dedicated references: fDMG 0.85 +/- 0.05 -> 0.95 +/- 0.02 refs [32] [33] MNGC224 1.5 +/- 0.5e12 Msun -> 1.4 +/- 0.4e12 Msun refs [35] [36] fDMNGC224 0.85 +/- 0.05 -> 0.92 +/- 0.03 refs [30] [31] RNGC224 radius unchanged ref [34] DNGC224 2 537 000 +/- 50 000 ly -> 2 482 000 +/- 36 000 ly ref [29] Remove the mis-cited Reference 11 (Penarrubia, LMC) and Reference 12 (Veljanoski, M31 satellite plane) entries, which did not actually source the Andromeda mass. Add scaffold definition entries for the new galaxy references 29-36 (Li & Riess, Ibata, Sick, Licquia & Newman, Bland-Hawthorn & Gerhard, Nieten, Watkins/Evans/An, Zhang et al.); their full bibliographic citations remain to be completed (marked "citation a completer").

Consolidated reference-cleanup PR, as planned in #1706 — addresses both #1706 (reference taxonomy) and #1707 (galaxy constants) in one pass, so the newly allocated reference numbers don't collide.
#1706 — reference taxonomy

Milky Way and Andromeda shared identical mass / dark-matter values (copy-paste artifact) and several mis-attributed references.
