docs(handoff): picker universe merged, shipped and verified live — and a verify-block grep that matched its own test file

[ZacxDev]

Closes out rank 9 of handoff-mention-system-repos.md. Docs only — no code.

Rank 9 is DONE: #1369 (156b4927) merged, shipped to both hosts, and verified by
driving the real systemd unit on each (Result=success ExecMainStatus=0) rather
than by reading that the timer was scheduled. Workbench 392 universe rows / 52
picker-only; laptop 391 / 52.

⚠ That 1-row difference is correct, not drift — the universe unions LOCAL
CHECKOUTS, so the file is a per-host measurement. Written down because a future reader
comparing the two numbers would otherwise conclude a host was stale.

The correction worth reviewing

The previous handoff's "How to verify" block carried:

git -C ~/workspace/devrc ls-files | grep -c 'known_repos'   # must be 0

It returns 1 on a perfectly clean tree — scripts/tests/test_regen_known_repos.py
matches its own name. I shipped that line earlier today and caught it only by reading
what matched instead of the count.

Two failure modes, and the second is the bad one: a reader either chases a phantom
disclosure, or learns this check "always says 1" and stops reading it — on a check
whose whole job is catching a private-repo leak. Replaced with a query for the
artifact ((known_repos|known_universe)\.json$, must print nothing) plus the
content-based test, which is the authoritative check and is not name-based at all.

Also recorded: a timer being scheduled is not a timer that works — list-timers
proves systemd parsed the unit and nothing more; it never exercises the unit's PATH,
HOME, or whether gh is reachable from inside it.
