The "problem" is in how ansible registers results when using with_items.
It nests all of the results inside of a `results` key
Your second task could have been written to use:
- name: use shell to print list of file paths
shell: "echo {{ item }}"
with_items: "{{ files.results|map(attribute='stdout_lines')|list }}"
That would do it for you. That pulls the `stdout_lines` attribute out into
a list of `stdout_lines`, then with_items natively handles the flattening,
allowing you to loop over each individual item in the `ls` output.
There is some documentation about using register with a loop, which you can
find at
http://docs.ansible.com/ansible/playbooks_loops.html#using-register-with-a-loop
