Introduce arena_02 (Nebula) and arena_03 (Asteroid Field) alongside arena_01, listed in a new ArenaRegistry (scripts/arena_registry.gd) as the single source of truth for available arenas. Free Play lets the player pick an arena from the main menu; Match/Spectate each pick one at random per session; Training keeps its own fixed arena_01. Nebula gets an RL-style visual treatment: a near-invisible glass boundary material shared by all arenas, a baked equirect nebula sky texture, a drifting-dust particle system, and a Blender-modeled station/debris/planet decoration set. GameMode gains a _get_arena_scene_path() hook so modes can instantiate their arena in code instead of hardcoding it in the scene.
