TODO.md: drop work logs, keep only open work (closes #20)

Removes the Status section, which listed work already landed on next,
and the Next Step section, whose two items are done: the milestone PR
merged and the binary has run on a Mac. The Workflow section stays.

-# Status

-On `next`:
-
-- Repo standards (https://git.eeqj.de/sneak/rtnetmon/issues/1): the `script/`
-  entrypoints, the vendored `.golangci.yml`, and `REPO_POLICIES.md`.
-- Interface detection on Linux and macOS
-  (https://git.eeqj.de/sneak/rtnetmon/issues/2).
-- The fix for macOS VPN detection (https://git.eeqj.de/sneak/rtnetmon/issues/8).
-- Starlink status lines (https://git.eeqj.de/sneak/rtnetmon/issues/3).
-- A version stamp: built with `make build` or a plain `docker build .`, the
-  binary logs its git tag or short commit at startup
-  (https://git.eeqj.de/sneak/rtnetmon/issues/10).
-- CI that runs `script/cibuild` on every push to a branch
-  (https://git.eeqj.de/sneak/rtnetmon/issues/12).
-
-# Next Step
-
-- `sneak` merges the milestone PR, https://git.eeqj.de/sneak/rtnetmon/pulls/6,
-  carrying `next` into `main`.
-- A first run on a real Mac of what is on `next` now. The fix for
-  https://git.eeqj.de/sneak/rtnetmon/issues/8 has not run on a Mac yet;
-  `sneak`'s first run on his Mac is its test.
