M1: build shared 2-tread bot; rewire TreadPart to seat-based gating
- Rewrote TreadPart: seat-based input gating (was mis-wired to NetworkObject IsOwner, which needs per-tread ownership that NGO forbids for nested NetworkObjects). Both treads now share the chassis NetworkObject; a client drives the tread whose SeatManager seat it holds, host re-validates OwnsSeat on a RequireOwnership=false RPC. Also swapped to Keyboard.current (New input). - Moved SeatManager OnGUI below the connectivity panel (was overlapping). - M1_Arena: in-scene Bot NetworkObject = chassis (Rigidbody 60kg + NetworkObject + NetworkTransform + NetworkRigidbody + SeatManager) + Tread_L/Tread_R children (TreadPart, world offset +/-1.2 X for differential drive). - Solo-verified: bot auto-spawns in-scene, seat claim + input gating wired. Controls: W/Up throttle, Shift pivot, A/D lean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
