yuxuanhui 7e0f13d678 feat(selection): expose run sector aggregates and sector filter on results API
- sector_radar: add batch sector-count aggregation and sector member lookup
  over the strict last-good membership snapshot (postgres + in-memory fakes)
- selection: add SelectionSectorReader port, list_sector_counts use case,
  and sector_stock_codes filtering via run identity resolution; queries stay
  inside the selection context per ADR 0001
- http: add GET /api/v1/selection/sectors and forward sector param on
  /results and /runs/{run_id}
- fix stale positional args in pattern-scoring run tests; cover new behavior
  with read-service, application, and HTTP contract tests
