Release 2.11.0

[hiroshihorie]

Minor release. Main theme is video degradation preference alignment with the other SDKs, plus hardening around protobuf enums and the backup codec lifecycle, new DisconnectReason members, and a dependency refresh.

Changes

Added

• DisconnectReason members for newer server reasons (roomClosed, migration, sipTrunkFailure, ...)
• DevelopmentTokenSource, replaces the deprecated SandboxTokenSource

Changed

• Default degradation preference follows track source (camera keeps framerate, screen share keeps resolution), also applied to the backup codec sender
• Unknown protobuf enum values from newer servers fall back to safe defaults instead of erroring
• Protocol definitions v1.50.4
• Dependency updates (device_info_plus 13.x, connectivity_plus 7.3.1, dart_webrtc 1.8.1, synchronized 3.4.1, uuid 4.6.0)

Fixed

• Backup codec state cleared on unpublish and full reconnect, backup codecs republish correctly after reconnect
• Room.getSid() resolves when the room sid arrives after the join response
• DegradationPreference.disabled maps to maintainFramerateAndResolution as WebRTC defines it
