PlayServ.Sdk.Arena 1.0.0-dev.1781

The arena-game framework: a genre-level room base (ArenaRoom2D) that composes the PlayServ SDK systems — movement, projectile combat, world items, presence — and owns the sim loop, the world adapter, and the standard room verbs (join/input/respawn/leave/poll). A game subclasses it and supplies only decisions: the velocity model, damage rules, spawn placement, identity, and the snapshot field-map.

No packages depend on PlayServ.Sdk.Arena.
