Kjell Tore Guttormsen 24775f4493 feat(linkedin-studio): RE-R1 — item-schema (B1) + triage-scorer (B2) as tested code behind CLI seam [skip-docs]
Lift the research engine's deterministic core out of agents/trend-spotter.md prose
into pure, tested TypeScript under scripts/trends/, behind a CLI seam the agent calls.

- B1 src/item.ts: TrendItem ingress envelope + normalizeItem/normalizeItems
  (required-field validation, topic normalize+dedupe via store's normalizeField,
  optional publishedAt ISO-validate). No id (store derives it); no store bridge
  (capturedAt injection is R2).
- B2 src/score.ts: per-mode weight consts mirroring the SSOT
  (references/trend-scoring-modes.md), composite (weighted sum, [1,10] guard),
  band (5-band map + exact SSOT action strings), triage (keep>=threshold, rank desc,
  annotate composite+band). Owns ONLY the arithmetic; the five judgment scores stay
  model-side.
- CLI normalize/score: JSON payload on STDIN, JSON to stdout (the existing --json
  output toggle is untouched); exit 2 on bad invocation, 0 otherwise.
- Wire trend-spotter.md to name 'src/cli.ts score' as the deterministic-step owner
  (prose pointer; the agent still supplies the five scores). Domain-general.
- Gate: TRENDS_TESTS_FLOOR 24->62; new unconditional Section 16g (score.ts both-mode
  weight-sets + trend-spotter scorer-pointer + non-vacuity self-test);
  ASSERT_BASELINE_FLOOR 84->87.

TDD: logic-RED proven (33/34 item+score fail on assertions, not module-not-found),
then GREEN (trends suite 62/62); CLI RED 2/4 -> GREEN 4/4. Full gate 102/0/0.
No store-schema change (SCHEMA_VERSION stays 1).
