Add IAuthorizationHeaderProvider2 with metadata-returning header-creation methods#257

Conversation
…tion methods Adds an additive numeric-suffix extension to IAuthorizationHeaderProvider that returns the rich AuthorizationHeaderInformation (header value, binding certificate, and token-acquisition metadata) as an OperationResult instead of a bare header string. Provides a rich counterpart for each of the three base methods, each taking the SAME input parameters as its base method: - CreateAuthorizationHeaderInformationForUserAsync (mirrors CreateAuthorizationHeaderForUserAsync) - CreateAuthorizationHeaderInformationForAppAsync (mirrors CreateAuthorizationHeaderForAppAsync) - CreateAuthorizationHeaderInformationAsync (mirrors CreateAuthorizationHeaderAsync) A single implementation can serve both interfaces and existing string-returning callers are unaffected. Public API entries added across all target frameworks. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

What
Adds
IAuthorizationHeaderProvider2 : IAuthorizationHeaderProviderwith a metadata-returning rich counterpart for each of the three base header-creation methods. Each returnsOperationResult<AuthorizationHeaderInformation, AuthorizationHeaderError>(header value, binding certificate, and token-acquisition metadata) instead of a barestring:IAuthorizationHeaderProvider)IAuthorizationHeaderProvider2)CreateAuthorizationHeaderForUserAsyncCreateAuthorizationHeaderInformationForUserAsyncCreateAuthorizationHeaderForAppAsyncCreateAuthorizationHeaderInformationForAppAsyncCreateAuthorizationHeaderAsyncCreateAuthorizationHeaderInformationAsyncEach rich method takes the same input parameters (names, types, defaults) as the base method it mirrors — only the return type differs.
Why
The token-acquisition metadata surface (#253) added the rich POCOs (
AuthorizationHeaderInformationwithMetadata/BindingCertificate,AuthorizationHeaderErrorwithMetadata/FailureDetails) and aDownstreamApiOptions-based rich provider (IBoundAuthorizationHeaderProvider). What remained was a rich (metadata-returning) counterpart for the scopes/string-based user, app, and unified entry points on the core provider. This interface fills that gap.Design
