MusicThing 0.2.5 — Meme trio and AFK redesign

Add Deadpan, Zest and Chiseled with distinct vector heads, body silhouettes and coffee/joke-notes/mirror-check quiet activities. Twenty-five choices now participate in the picker and rotating group scenes.

Redesign AFK around the supplied gamer reference: bald forehead, sparse messy side hair, small glasses, irregular stubble, gray-and-black shirt, broad build and hairy forearms. Use approved pose B (scratch and central mixer) during music and pose D (keyboard) during quiet mode.

Remove redundant DJ prefixes from display names. Preserve saved character IDs, alphabetical ordering, Guest Set and Dance Party at the end, and the eight-character Dance Party cap. Update illustrated active/quiet galleries.

87 automated checks pass. Updated client files installed and verified on the connected Car Thing.
