feat(llm): add Qwen3-VL-8B and Qwen2.5-Coder support, update CUDA config

- Add new `qwen3-8b-vision` model with multimodal support using mmproj file
- Add new `qwen2.5-coder-7b-instruct` model with FIM enabled via `--fim-qwen-7b-default`
- Update CUDA device usage from `CUDA0` to `CUDA1` for `olmoe-7b-instruct` and `phi-mini-8b-instruct`
- Upgrade llama.cpp to version 7426 with updated hash and CUDA architectures (61;86)
- Add Copilot acceptance shortcut `<C-J>` in insert mode and disable tab mapping
- Improve cache type settings across multiple models for better performance
