New mob footstep system (59 → 105 events) BETA feature
- Added entity.*.step for all 46 previously-uncovered mobs: armadillo, baby_chicken, baby_horse, baby_pig, baby_wolf, bogged, camel, camel_husk, chicken, chicken_picky, copper_golem (+oxidized/weathered), cow (+moody), creaking, drowned, endermite, frog, goat, hoglin, horse, husk, iron_golem, llama, panda, parched, parrot, pig, piglin (+brute), polar_bear, ravager, sheep, silverfish, skeleton, sniffer, spider, stray, strider, warden, wither_skeleton, wolf, zoglin, zombie, zombie_villager
- Built from 11 footstep "archetypes" grouped by body/movement type rather than 46 fully separate recordings — heavy_mammal, metal_clank, undead_shuffle, skeletal_rattle, small_skitter, canine_trot, nether_beast, warden_ominous, creaking_wood, spider_skitter, armadillo_shell — each mob tuned with its own pitch/volume (e.g. baby variants pitched up, iron_golem pitched down and boosted for weight, oxidized/weathered copper golem duller than base)

# Audio pipeline
- 18 new block materials + 11 mob archetypes: all mono, 44.1kHz, Vorbis — matches the rest of the pack's spec
