Subject: [PATCH] Add HeaderQueryBehavior and update DI configuration

Added `HeaderQueryBehavior<TRecAction>` to handle header query
processing in the MediatR pipeline. Updated the `DependencyInjection`
class to register `HeaderQueryBehavior<>` alongside
`BodyQueryBehavior<>` in the MediatR configuration. The new behavior
currently throws a `NotImplementedException` as its logic is pending
implementation.
