year disambiguates same-name subjects during auto-scrape
- structure filter: hard-converge candidates on equal episode numbers and

offset; rebinding a series resets stale danmaku episode identity
users.role (first registrant admin), app_settings store plaintext AppId/Secret, admin-only settings API and UI section, runtime credential override in @app/danmaku.
