Select `wkt/addr_unpacking` in `pyproject.toml` and lock `tractor`
at `a966928dead4cbf369ad244834ce9dbe988ac8ca` in `uv.lock`.
Keep the existing PR94 application/test tree as the landing base
for the original downstream consumer fixes.
Also,
- resolve `setproctitle` 1.3.8 while retaining `polars` 1.36.0,
- record the dependency selection and original-history previews
with their Prompt-IO provenance.
