feat: Optimize C# binding interop (#488)

Browse Source 
- Introduce Utf8Marshaller helpers and SafeHandle wrappers so the managed API centralizes UTF-8 conversions and lifetime management for native pointers.
- Update Engine, Compiler, CompiledPolicy, SchemaRegistry, and TargetRegistry to rely on the new marshaller/safe handles, tightening disposal and reducing transient allocations during interop calls.
- Add allocation guard coverage in Regorus.Tests and report bytes/op in the compiled policy benchmark to surface future regressions.
