docs: show include_org_repos in the runnable examples

The input reached both reference tables but neither example, so anyone
copying the workflow YAML or the CLI invocation would not learn the knob
exists. Add it to the Action example with a note on when to flip it, and
add a second CLI example alongside the existing one.

Add CLAUDE.md recording the five surfaces a config knob has to reach —
flag, action input, entrypoint translation, README tables *and*
examples, architecture doc — since the examples are the step that got
missed here. Also note the demo gallery's hardcoded card list and the
GitHub API ceilings the fetch pipeline works around.
