MINE PIECE: NEW ERA — 1.87.1
Build: NE-1871-RIGHT-SHOULDER

Loki rests Ragnir over his RIGHT shoulder, with his right hand on the handle.
The shared idle, walking, sprinting and three reference attack animations use
the revised hold. Wind-up and recovery paths pass around his right side.
All 1.87.0 combat behavior and cumulative content are retained.

Verification: actual runtime grip/FX checks passed; 120 Hz animation samples
keep the handle attached and retain fixed limb lengths. Exact cuboid checks
found no hammer/head intersections in the three reference moves. Shaft checks
found no intersections through the head or torso. Render previews were updated.
This patch has not received a graphical Minecraft client playtest.

Replace the previous New Era JAR on both client and server. Keep one New Era
JAR and the existing MinePiece/animation dependencies. /newerabuild reports
1.87.1 and NE-1871-RIGHT-SHOULDER.
