New and existing users now see a built-in "Claude Official" / "OpenAI
Official" / "Google Official" entry in their provider list, so switching
back to the official endpoint is one click away instead of buried in the
README.
- New providers_seed.rs holds the three seeds (id, name, settings_config,
icon) keyed by AppType, with a single is_official_seed_id() helper that
scans OFFICIAL_SEEDS so the id list has one source of truth.
- Database::init_default_official_providers() runs once per database
(gated by an official_providers_seeded setting flag), appends each seed
to the end of the sort order, and never touches is_current.
- Startup also auto-imports the live config (settings.json / auth.json /
.env) as a "default" provider before seeding, so users with an existing
manual config don't lose it when they click the official preset.
- Database::has_non_official_seed_provider() replaces the get_all_providers
call in import_default_config's gating check with an id-only scan,
dropping the N+1 endpoint sub-queries from every startup.
