Add functional custom buttons/panels to any site via prompts

It turns a plain-language request like “add a HubSpot button next to this name” into a live UI element injected into the page and persisted across visits — no separate dashboard, real API calls, and editable placement. The smart bits are the DOM parsing + selector/pattern matching that make features reappear on matching pages and the use of Shadow DOM to avoid style collisions. Real concerns: putting integration keys in extension storage and brittle behavior on heavy SPAs/CSPs are obvious trade-offs.
