feat(planning): keep a re-issued interview question's history across supersede chains #9721

Refs #5796

Depends on

• none: on the frontier now

Outcome

A question re-issued by archive-and-replace keeps its history (gap G6):

• The page shows the full chain ("Asked as Q5 in round 2, then Q35"), not only the immediate predecessor.
• The carried-rounds count starts from the chain's first question.
• The "Still open from earlier rounds" section is pinned in every view, not only Rounds.
• A one-for-one mass supersede warns and points to revise.
• archive clears any hold on the archived question.

Key interfaces

• Interview page: plugins/planning/surface/index.html; page server: plugins/planning/surface/server.py
  (record(), derive_states); round CLI: plugins/planning/surface/round.py behind round.sh;
  exporters: plugins/planning/surface/exporters.py.
• The interview skill's surface contract, plugins/planning/skills/interview/context/surface.md, documents
  every new op, field, setting and refusal.

Done when

• A page test on a three-link chain shows both earlier ids and the carried count from the first.
• A page test finds the carried section in Groups view.
• A round test superseding 3 questions one for one prints a warning naming revise.
• A round test archives a question holding a waiting hold and finds the hold cleared.
• scripts/run-test-file.sh plugins/planning/surface/test_server.py exits 0.
• scripts/run-test-file.sh plugins/planning/surface/test_round.py exits 0.
• bash plugins/planning/surface/surface.test.sh exits 0, so a data dir without the new fields still loads, renders and exports.
• scripts/check-changelog-fragments.sh --check-required origin/main exits 0.
