chore(gallery): add GUI-Owl 1.5 2B variants

Add Q4_K_M and Q8_0 GGUF builds for screenshot interpretation and GUI
planning with llama.cpp. Include the F16 vision projector in both builds
and document installation and the separate action executor requirement.

Pin all downloads and verify SHA256 values against Hugging Face LFS
metadata and download headers.

+## GUI-Owl 1.5 2B Instruct
+
+GUI-Owl 1.5 uses Qwen3-VL to interpret screenshots and predict GUI actions.
+The gallery includes Q4_K_M and Q8_0 GGUF builds for llama.cpp, each with an F16 vision projector.
+Both use the embedded chat template and a 32,768-token context by default.
+LocalAI serves the model; a separate agent must execute its predicted actions.
+
+Install with automatic variant selection:
+
+```bash
+local-ai models install gui-owl-1.5-2b-instruct
+```
+
+To select Q8_0 explicitly:
+
+```bash
+local-ai models install gui-owl-1.5-2b-instruct --variant gui-owl-1.5-2b-instruct-q8
+```
+
+Send screenshots as image content in chat requests, as described in [GPT Vision](/features/gpt-vision/).
+See the [model card](https://huggingface.co/mPLUG/GUI-Owl-1.5-2B-Instruct)
+and [GGUF downloads](https://huggingface.co/mradermacher/GUI-Owl-1.5-2B-Instruct-GGUF).
