	// CursorPath, when non-empty, causes Stream to atomically rewrite the
	// cursor file after processing. The caller is responsible for seeking the
	// underlying reader to the offset recorded in the cursor file before
	// calling Stream; CursorStartOffset must be set to that same offset so
	// Stream can compute the absolute file position when writing the cursor.
	//
	// Design note: we keep Stream's signature as io.Reader (rather than
	// *os.File) so tests can pass bytes.Buffer or strings.Reader without
	// touching the filesystem. The caller in watch.go handles the actual
	// os.File seek; we track bytes consumed here via a counting wrapper.
