The server now writes a default crabidy-server.toml on first start listing
every provider:
providers = ["tidal", "youtube", "fs", "crabidy", "orphans"]
Removing a name disables that provider — it no longer mounts and drops out
of the library; its own config file is left unread. An absent providers key
(a deleted line, or a fresh install with no file) enables all of them, so a
server never silently loses its whole library. Disabling crabidy also drops
orphans, which is a view over the store.
ServerSettings gains the providers list, provider_enabled/provider_toggles,
and ensure_default (best-effort first-run seed). ProviderOrchestrator::init
becomes ::build(ProviderToggles), gating each provider; the tidal client is
now Option like the others (still fatal-on-error when enabled, skipped when
disabled). README and the mdbook document the list.
