1.44.6

(fix): Fix generated Go failing to compile for APIs that use literals. Undiscriminated union members whose literal value is not a valid Go identifier (e.g. starting with a digit) now produce a valid exported field name, literal query parameters are no longer double-quoted, and literal path parameters are now passed as their concrete value in dynamic snippets instead of nil.

(fix): Support endpoints with a stream-condition (stream-parameter) response. The v1 generator now handles the non-streaming variant instead of aborting, and the v2 generator includes the streamer helper files when an endpoint exposes a stream-parameter response.
