Residual from RCLK-WP-0005-T01. railiance01 already runs a single
systemd-timesyncd against Ubuntu default NTP, UTC, synchronized. That unit is
not in S1 IaC. railiance-hosts is superseded; do not duplicate the tree there.

Wait for RCLK-WP-0002's UTC/leap/quality contract before choosing servers or
holdover. Do not install chrony alongside timesyncd.

## Declare the adopted daemon

```task
id: RAIL-HO-WP-0013-T01
status: wait
priority: medium
```

Version systemd-timesyncd (not chrony) in railiance-infra: enabled unit,
NTP/FallbackNTP, restricted listeners, health export. Lint/render only until
RCLK-WP-0002 and RCLK-WP-0005-T02 authorize live apply. No second daemon.
