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

Brings README.md and TODO.md in line with REPO_POLICIES.md and with what is on next. The README's first line now names routewatch, what it is, its MIT licence and its author, @sneak; the License section says MIT and links LICENSE; a new Author section names @sneak.

TODO.md's Status, Next Step and Future Steps now describe next as it is: it waits for sneak to merge the milestone PR, after which the upaas deploy and the run under a real 5 GiB limit are his. Completed Steps gains a line for each issue that landed without one.

Docs only. make fmt formats only Go here, so the markdown was wrapped by hand.

Model: opus-5-5

 # Status
 
-pre-1.0. No git tags. Runs in production-style Docker deployment, but
-the policy compliance branch (repo-policies-compliance, make check
-passing, clean tree) is unmerged to main and the CI workflow is missing.
+pre-1.0. No git tags. The Docker build runs the format check, the linter
+and the tests, and the Gitea workflow runs that build on every push. The
+image sets memory ceilings for a 5 GiB container (README "Memory") and the
+README says how to run it under upaas (README "Running under upaas"). A
+35-hour run of `3898daa` on the live feed peaked at about 1 GiB, without a
+container memory limit.
 
 # Next Step
 
-Merge repo-policies-compliance into main (3 commits: policy files and
-.gitignore, Makefile targets fmt-check/check/docker/hooks, gofmt pass),
-then add .gitea/workflows/check.yml as a small follow-up commit so CI
-runs make check on main.
