Defined in:

Overview

Pure-data handle to an extracted OHOS NDK installation. Discovers the four critical paths the build needs (toolchain cmake, clang, sysroot, binary-sign-tool), exposes them as Pathnames, and can invoke ext/ohos/setup-ndk.sh to populate the directory if missing.

Does NOT run any NDK binary itself -- that's the caller's job. This keeps the class testable without qemu/binfmt setup: specs just touch empty files at the expected paths and assert accessors.
