v0.6.0

[v0.6.0] - 2025-02-11

Added

• Added token-based pagination to GET /orders, GET /products,
  GET /orders/{order_id}/statuses, and POST /products/{product_id}/opportunities.
• Optional and Extension STAPI Status Codes "scheduled", "held", "processing", "reserved", "tasked",
  and "user_canceled"
• Asynchronous opportunity search. If the root router supports asynchronous opportunity
  search, all products must support it. If asynchronous opportunity search is
  supported, POST requests to the /products/{productId}/opportunities endpoint will
  default to asynchronous opportunity search unless synchronous search is also supported
  by the product and a Prefer header in the POST request is set to wait.
• Added the /products/{productId}/opportunities/ and /searches/opportunities
  endpoints to support asynchronous opportunity search.

Changed

• Replaced the root and product backend Protocol classes with Callable type aliases to
  enable future changes to make product opportunity searching, product ordering, and/or
  asynchronous (stateful) product opportunity searching optional.
• Backend methods that support pagination now return tuples to include the pagination
  token.
• Moved OrderCollection construction from the root backend to the RootRouter
get_orders method.
• Renamed OpportunityRequest to OpportunityPayload so that would not be confused as
  being a subclass of the Starlette/FastAPI Request class.

Fixed

• Opportunities Search result now has the search body in the create-order link.
