internal/link and internal/link/direct were a single-implementation
abstraction layer where directLink mechanically proxied every method to
transport.Transport — only Features() lived above transport.Transport,
and even that was a Features() alias. Six layers of plumbing for zero
behavioural value.
Drop the layer entirely:
- muxconn.Conn now takes a transport.Transport directly.
- server.Server and client.Client store transport.Transport, call
transport.New, and expose Features() through transport.Transport's
built-in method.
- server.Config and client.Config lose their Link string field.
- session.Config loses Link + validateLink + ErrLinkRequired/ErrUnsupportedLink.
- config.File and config.Profile lose the link YAML key.
- pkg/olcrtc/tunnel.Config loses Link.
- mobile drops defaultLink, SetLink, and mobileConfig.link.
Two e2e tests that exercised link.New directly are renamed to call
transport.New (TestTransportCreatesAllProviderTransportCombinations and
TestTransportConnectsFastProviderTransportMatrix); behaviour is unchanged.

Each auth.Provider now declares DefaultServiceURL() so callers do not
need to know service-specific endpoints. ApplyAuthDefaults fills Engine
and URL from the provider before validation runs — explicit flags always
win, and providers with no default URL require -url to be set explicitly.

Break CLI backwards compatibility as planned for refactor/universal-carrier:
- Drop -carrier flag; add -auth (auth provider name), -engine (engine
name for -auth none), -url and -token (SFU endpoint + access token for
direct/none auth mode).
- session.Config.Carrier → Auth + Engine + URL + Token.
- session.Gen() is now generic: auth.Get(cfg.Auth).(auth.RoomCreator)
replaces the hard-coded switch on carrier names.
- Register a "none" carrier in builtin (registerDirect) that bypasses
auth and connects directly to any engine with caller-supplied URL+Token.
- auth/telemost.Provider.Issue now accepts a raw room-ID hash in addition
to a full https://telemost.yandex.ru/j/<id> URL.
- Plumb Engine/URL/Token from session.Config through server.Run,
client.Run/RunWithReady, bringUpLink, link.Config, transport.Config, and
carrier.Config so the "none" carrier has access to them end-to-end.
- Update all tests and mobile.go call sites.
