 * NIO-based file operations for local files on API 26+.
 * Uses kernel-level zero-copy (sendfile syscall) where possible,
 * avoiding user-space buffering.
 *
 * These functions are only for local file-to-local file operations (JavaFile).
 * SAF/ContentProvider backends use FileChannel via copyFileWithChannelFallback
 * (see Utilities.kt) with stream-based fallback.
