Svelte Agentation ports feedback loop to Svelte

This feels less like a novelty overlay and more like plumbing for a real AI-assisted design review loop. The feature set is small on purpose, but the routing and copy improvements make it more practical for day-to-day frontend iteration than a one-off demo.

• –Automatic route scoping solves a real nuisance: notes stay attached to the page they belong to instead of leaking across views
• –Hover previews and source-aware element inspection reduce the chance of sending an agent the wrong target or the wrong level of context
• –Multiple export modes, from compact to forensic, suggest it can serve both quick feedback and deeper debugging sessions
• –The dev-only, browser-only setup keeps the footprint light, but also makes it a workflow tool for local review rather than a general-purpose app layer
• –It is effectively a Svelte adaptation of Agentation’s feedback pattern, which makes the category feel validated rather than reinvented
