Patch Changes

• #504 `e9b2a9a` Thanks @threepointone! - Forward reasoning_effort and chat_template_kwargs onto binding.run(model, inputs)'s inputs object instead of silently dropping them into the options arg / REST query string. This fixes reasoning models (GLM-4.7-flash, Kimi K2.5/K2.6, GPT-OSS, QwQ) burning the entire output token budget on chain-of-thought with no visible content.

Both settings-level and per-call usage are supported:

// Settings-level
const model = workersai("@cf/zai-org/glm-4.7-flash", {
reasoning_effort: "low",
chat_template_kwargs: { enable_thinking: false },
});

// Per-call (overrides settings)
await generateText({
model,
prompt,
providerOptions: {
"workers-ai": { reasoning_effort: "low" },
},
});

reasoning_effort: null is preserved as-is (explicit "disable reasoning" signal). The two fields are also typed directly on WorkersAIChatSettings.

Closes #501.
