[Feature Request] Native [Ctrl] + [F] search shortcut within workflows (Prompts, LoRA models, etc.)

### Feature Idea

Is your feature request related to a problem? Please describe.When working with large, complex workflows in ComfyUI, it becomes very difficult and time-consuming to manually find specific elements, such as text within prompt nodes or specific LoRA models applied across the canvas.Describe the solution you'd likeI would like to suggest integrating a native [Ctrl] + [F] keyboard shortcut (and [Cmd] + [F] on macOS). Pressing this shortcut would open a search bar allowing users to search the entire workflow. It should highlight and locate:Specific text strings or keywords inside prompt nodes.Specific model names (such as LoRAs, Checkpoints, or VAEs) currently loaded in the nodes.

The issue targets the workflow canvas, prompt nodes, and model nodes containing LoRAs, checkpoints, and VAEs, but it names no files, tests, or existing entry points. Start by locating the canvas keyboard-shortcut handling and workflow data used by those nodes. Done should include Ctrl+F/Cmd+F search, highlighting or locating matching text and model names across the workflow.
