dsh-2d-model-picker: Select model and inference strength with a single drag

The native DSH model selector requires two steps to switch models and inference strength. dsh-2d-model-picker transforms this into a 2D grid where rows represent models and columns represent inference strength levels; simply drag to a combination and release to apply. Maintained by Fyerl, this plugin is licensed under the MIT License (version 1.0.1) and falls under the 'Model Inference' category. It can be installed by entering 'dsh-2d-model-picker' in Plugins → Add plugin, or via the CLI command `dsh plugin --profile web add dsh-2d-model-picker`, or through Custom plugin indexes. The plugin runs with the permissions of the current DSH process. Please check the source code and license before installation.
