[MCPE-240425] Bedrock Edition player animation issues

Description: On vanilla Bedrock (no resource/behavior packs), the following animation bugs occur:

Empty hand in first-person: No swing animation when attacking
Third-person movement: Head and body rotate together, arms don't swing
Spear: Incorrect first-person held position; no attack animation in either first or third person

Expected: Empty hand swing; independent head movement and arm swing in third-person; spear thrust animation

Observed: No empty-hand swing; head-body lock and static arms in third-person; spear lacks attack animation with wrong positioning

Steps to Reproduce: Vanilla Bedrock, new world, test empty-hand attack, movement, and spear attack in both views

Platform: Windows 11, Version 26.32
