VLMGenerationOptions class

VLM generation options — per-request sampling + prompt parameters. Sources pre-IDL: Kotlin VLMTypes.kt:103 (maxTokens, temperature, topP, systemPrompt, maxImageSize, nThreads, useGpu) Dart vlm_types.dart:127 (maxTokens, temperature, topP, systemPrompt, maxImageSize, nThreads, useGpu) RN VLMTypes.ts:21 (maxTokens, temperature, topP) Web VLMTypes.ts:28 (maxTokens, temperature, topP, systemPrompt, modelFamily, streaming) C ABI rac_vlm_types.h:143 (max_tokens, temperature, top_p, stop_sequences, num_stop_sequences, streaming_enabled, system_prompt, max_image_size, n_threads, use_gpu, model_family, custom_chat_template, image_marker_override)

top_k is included to align with the other text generation services (LLM / chat) even though no current VLM SDK exposes it; the C ABI's llama.cpp backend already supports top_k internally.
