Optional parameters with an OpenAPI `default` no longer have that value filled in client-side; unset parameters are omitted so the server applies its own default.

README snippets and generated tests reference SDK enum members such as Model::CLAUDE_SONNET_5 instead of string literals. Also picks up the user profiles access_type field, embeds the OpenAPI spec in scripts/mock, and sends the VERSION constant in X-Stainless-Package-Version.

Move the hand-written test files out of the tests/ root so the layout mirrors src/: middleware pipeline and SSE tests under tests/Core, RefusalFallbackMiddleware tests under tests/Lib/Middleware, and MessageAccumulator tests under tests/Lib/Streaming; tidy a few comments along the way. Replace the fallback fixture-replay runner, which needed an external fixture directory and always skipped here, with hand-written streaming cases over three checked-in SSE captures (fixtures/refusal-fallback), so the streaming path of RefusalFallbackMiddleware is covered the way the non-streaming path already is.

The request transformer round-tripped the query string through parse_str()/http_build_query(), which re-indexes array params and re-encodes values. Carry the encoded query through unchanged and only strip the dropped key. Co-authored-by: claude[bot] <209825114+claude[bot]@users.noreply.github.com> Co-authored-by: Claude <noreply@anthropic.com>
