feat(sessions): indexação multi-fonte Hermes + OpenCode com fix TypeScript

- Novos indexadores hermes-indexer.ts e opencode-indexer.ts para unificar
  sessões Claude, Hermes Agent e OpenCode num único sessions.db
- SessionMeta alargado: source (obrigatório), model, input/output_tokens,
  estimated_cost; project_path/jsonl_path agora nullable
- Fix TS: tipos explícitos, guard jsonl_path null, dependências instaladas

Security Audit (Regra #47):
- npm audit executado — 0 vulnerabilities após fix
- vite 7→8.0.16 (breaking upgrade, resolve esbuild CVE GHSA-gv7w-rqvm-qjhr)
- vitest 4.0.18→4.1.9 (resolve esbuild interno CVE GHSA-gv7w-rqvm-qjhr)
- shell-quote override ^1.8.4 via package.json#overrides (CVE GHSA-w7jw-789q-3m8p)
- react-router, joi, qs, form-data, ip-address, js-yaml resolvidos via npm audit fix
