Add abstract MemoryBase base class with typed Read<T>/Write<T>, array IO, string IO, and relative/absolute addressing. Uses MarshalCache<T> to branch between blittable (MemoryMarshal) and marshal-required paths. Add ExternalReader (out-of-process via ReadProcessMemory/WriteProcessMemory) with SafeMemoryHandle lifecycle management. 11 new tests: ImageBase, Read/Write of int/byte/long/struct, byte array, int array, struct array, invalid address, dispose, double-dispose. All passing (total: 30).
