Fix: Godot C# Array Passed by Ref Allocates Managed Copy

Hot path: pass array; profiler shows 1KB allocation per call.

Pass by value

Marshaling once; no per-call boxing. Faster for hot paths.

Or use System.Array internally

Convert at boundary; use native C# types inside. Manual marshalling but cheap.

Profile allocations

.NET memory profiler. Per-call allocations surface immediately.

“Cross-language marshalling has cost. The cost is real on hot paths.”

For hot paths in Godot C#, the marshalling cost is the dominant overhead. Profile; reduce; ship.
