fix(ci): repair slow sl test and sync uv.lock to 0.16.0 (#345)

* test(sl): assert predefined_measures_only in slow sl query test

The slow-only sl query test asserted the outgoing compute.query() request
with an exact nested query object, so the predefined_measures_only flag
added by the semantic-layer-only query policy (#334) broke the match and
turned the Slow TypeScript tests CI job red on main.

* chore: sync uv.lock ktx-sl/ktx-daemon to 0.16.0

The 0.16.0 release bumped the pyproject versions but left uv.lock pinning
the editable ktx-sl/ktx-daemon packages at 0.15.0.
