/**
* Seeds electionTally / electionCandidateVote / electionCandidate from TSE
* open data (Bahia scope). Default year: 2022 (full ticket). Historical years
* 2014/2018 import deputado_federal + presidente + governador turno 1 (E2
* federal trend series + E8 majoritarian baseline for teto do campo/roll-off
* validation across cycles). Skips deputado_estadual for 2014/2018 — no
* consumer needs the state-assembly race historically. The country-wide
* (non-BA) files are always loaded too — see the inline comment above
* `voteBa`/`voteBr` below for why (presidente is BR-scope in TSE's data).
*
* Provenance (do not strip):
* - Portal 2022: https://dadosabertos.tse.jus.br/dataset/resultados-2022
* - Portal 2018: https://dadosabertos.tse.jus.br/dataset/resultados-2018
* - Portal 2014: https://dadosabertos.tse.jus.br/dataset/resultados-2014
* - Portal candidatos: https://dadosabertos.tse.jus.br/dataset/candidatos-{year}
* - CDN zips: https://cdn.tse.jus.br/estatistica/sead/odsele/{family}/{family}_{year}.zip
* - License: Creative Commons Atribuição (dados abertos TSE)
* - electionCandidateVote.votes ← QT_VOTOS_NOMINAIS (votos apurados; validade no tally)
* - v1: only voteType=nominal (no votacao_partido_munzona / legenda rows)
*
* Pinned SHA-256 (update after verifying a fresh download):
* - 2014/2018: log-only until first verified import in CI/local
* - 2022: log-only (existing deployments may have cached zips)
*
* Safety: refuses non-local DATABASE_URL unless ALLOW_REMOTE_DB=true.
* Idempotent: replace-by-scope (year, office, turn) via drizzle transaction.
*
* Usage:
* pnpm db:seed:tse
* pnpm db:seed:tse -- --year=2018
* pnpm db:seed:tse -- --year=2014
* ALLOW_REMOTE_DB=true pnpm db:seed:tse
* TSE_CACHE_DIR=./data/tse pnpm db:seed:tse
