1.2.47: restored the exact 1.2.45 Radiant crossbow geometry/UV/texture mappings; reset loading _0/_1/_2 rotations to the authored Divine Zephyr rotation while retaining user-selected loading placement/scale; adds a HeldItemRenderer client mixin so the custom Radiant Crossbow is treated as a vanilla crossbow for first-person crossbow-specific render checks only. Wings remain (0,0.8,0.8).
