/**
 * Resolves the path to the `adb` binary.
 *
 * Priority:
 *   1. ADB_PATH env var (explicit override)
 *   2. ANDROID_HOME / ANDROID_SDK_ROOT env vars + /platform-tools/adb[.exe]
 *   3. Platform-default SDK locations (Android Studio defaults)
 *   4. `adb` from PATH (fallback — works when adb is on PATH, e.g. macOS Homebrew)
 *
 * Result is memoized: the first call probes the filesystem, subsequent calls
 * return the cached path. Tests call `_resetCacheForTests()` to clear it.
 *
 * Throws AdbNotInstalledError with the list of probed paths when nothing works.
