HDF / HarmonyOS: mapping driver IPC and Linux userland compatibility

The HDF / HarmonyOS investigation maps the Driver Foundation's user-to-kernel IPC path and tests selected HarmonyOS libraries on Linux. It records the HDF_WRITE_READ ioctl, HdfWriteReadBuf layout and I2C command IDs, supported by harness code, a kernel stub and QEMU experiment logs.
