fix: resolve build errors in research integration

- Add stub methods to JSONLStore for Store interface compliance
- Fix import conflict in research.go (rename agent import)
- Fix TypeScript type imports (use import type)
- Fix launcherFetch response handling (call .json())
- Remove unused imports in research-page.tsx
- Fix research-reports.tsx timestamp reference
