dotpro progress callback — tag prediction

The progress output mode ships a custom stdout callback (plugins/callback/dotpro_progress.py) that pins a per-role region — one line per role with a changed count and a task/ETA bar — and predicts the role list up front from hand-rolled tag rules. That prediction is correct for the common case and wrong at the edges; this collects the remaining work.

Tag prediction

The up-front role prediction uses hand-rolled never/always rules that miss the all/tagged/untagged selectors — a --tags untagged run predicts no roles — and will drift when ansible-core changes tag precedence.

• Align the prediction with Ansible's real tag evaluation. Taggable.evaluate_tags is the reference implementation, but it wants all_vars and mutates task tags, so it needs care when called from a play-start callback.
