Sable: Sure Footing 1.2.0

Now covers more than the player:

• Non-player entities (item drops, XP orbs, mobs, boats...) are carried through airborne arcs on moving/rotating contraptions, server-side. Items dropped while riding a contraption inherit its velocity and land where you dropped them. Mobs turn with the deck (rotate_entity_yaw).
• Particles (smoke, flames, block-break debris) stay anchored to the contraption they spawned on instead of being flung tangentially after half a block of drift.
• New per-world server config (serverconfig/surefooting-server.toml) with strengths, timeout, exit distance, and an entity blacklist; anchor_particles client option.

The player and particle fixes work client-side even on servers without the mod; the entity carry needs the mod on the server. Requires Sable 2.0+ on NeoForge 1.21.1.
