[Cross-cutting/feat] Cross-field discovery surface — when discussion in field A spawns work in field B, link both field landing pages done

← Percolation Engine
Quest: Percolation Engine (f80549eb-38d) + Open Questions as Ranked Artifacts (b307ad54-a95). The system's interesting moments are when work in one field illuminates another. Make those moments visible. Acceptance: - Cross-field detector: nightly job scans artifact_provenance + artifact_links for chains where the source field_tag != target field_tag. - Per-pair surface: at /science/ show a 'Cross-pollination from ' card listing the bridging artifacts (e.g., 'a connectomics paper informed an aging hypothesis'). - Bidirectional: same card appears on /science/. - Score: cross-pollination edges are scored on novelty (rare field pair) + impact (downstream artifact citations). Top 10 surfaced; full list at /science/cross-field. - /api/cross-pollination?from=&to= returns ranked edges. - Spec: docs/planning/specs/cross_field_discovery.md. Why now: SciDEX is most valuable when it surfaces non-obvious connections across fields — that's the value above 'just another wiki'. This task makes the surfacing explicit.
