fix: expose setConnectionMode publicly with FDv2 overloads as @internal

The public API shows setConnectionMode(mode: ConnectionMode) and
getConnectionMode(): ConnectionMode. The FDv2-specific overloads
accepting FDv2ConnectionMode and undefined are stripped from
declarations via @internal + stripInternal.
