README: license and author up front; bring TODO.md up to date (closes #38)

REPO_POLICIES.md asks the README's first line to name the license and the
author, and for License and Author sections; the README had neither up
front, its License section only said "See LICENSE file.", and it had no
Author section.

TODO.md's Status, Next Step and Future Steps still described the unmerged
repo-policies-compliance branch and a missing CI workflow. They now say
what is true of next, and Completed Steps gains a line for each issue that
landed from 2026-09-21 on without one. The next step is not decided, and
Next Step says so.
