memory: snapshot — althing 3.2.0 deployed; uv tool install is a silent no-op

forseti requested the deploy, operator-approved and tagged at c4ede0f.
All three steps landed on nh3-dev and verified: force reinstall to 3.2.0
with seven binaries, herald restart, skill sync.

The durable lesson is the trap in step 1. `uv tool install .` matches on
the source spec rather than its contents, so on a box that already had
the tool installed from that path it prints "already installed" and exits
0 having done nothing. Following the runbook literally would have left
the new binary absent with every command reporting success. Always use
--force when reinstalling from a local path.

Also recorded: the pane-route migration revoked exactly four routes,
verified by splitting on channel= before the restart rather than by
auditing fields (all twelve route files lack the new fields, so a field
audit over-counts). The four affected agents were deliberately not
notified, per the standing rule against unsolicited fleet broadcast, and
that is surfaced to the operator instead.

And this closes an open question from earlier today: the waiter that died
with status "killed" was CC 2.1.257 reaping detached tasks, which is the
premise 3.2.0 exists to address.
