Migrate from v1

Version 2.0.0-beta.1 keeps RdpControl as the main entry point, but the configuration model now distinguishes between embedded and external sessions.

Breaking changes and additions:

• RdpClientConfiguration.SessionMode selects embedded vs external hosting.
• RdpClientConfiguration.External contains launcher, credential, temp-file, and cleanup settings.
• RdpClientConfiguration.RemoteApp is the new dedicated model for RemoteApp publishing. Do not overload Program for that purpose.
• ConnectedEventArgs and DisconnectedEventArgs now expose SessionMode.
• External mode does not expose an IRdpClient instance because the session is hosted by a separate process.
• Security configuration now includes both high-level modes (RemoteCredentialGuard, RestrictedAdminMode) and low-level flags (DisableCredentialsDelegation, RedirectedAuthentication, RestrictedLogon).
• Invalid mixed-mode combinations are now rejected during validation instead of being silently ignored.

See Support Matrix for the supported feature split between embedded and external sessions.
