Add manage_material tool documentation and fix MaterialOps texture property checks

- Add comprehensive ManageMaterial tool documentation to MCPForUnity/README.md
- Add manage_material to tools list in README.md and README-zh.md
- Fix MaterialOps.cs to check HasProperty before SetTexture calls to prevent Unity warnings
- Ensures consistency with other property setters in MaterialOps
