ship: fix evaluator column + correct contributor attribution

- Add domain_agent and domain_model to pr-lifecycle API response (data was
  queried but dropped before serialization — evaluator column showed blank)
- Show model name tag next to evaluator (Gemini Flash, GPT-4o, etc.)
- Re-attribute 1201 "pipeline (self-directed)" PRs to @m3taversal — these
  were Cory-directed, not autonomous overnight research
- Re-attribute 252 NULL PRs to @m3taversal
- Fix extract.py defaults: new PRs without proposed_by default to @m3taversal
- Fix backfill script defaults: extract/ branches → @m3taversal, not
  "pipeline (self-directed)"
- Only agent-named branches (rio/, theseus/, etc.) from research-session.sh
  remain as "(self-directed)"
