fix(deps): bump @tanstack/dom-vite to 0.1.0-alpha.6 for NPM stats toggle fix

Pulls in the shim's useEffect cleanup-at-run-time fix (shipped in
@tanstack/react-dom@0.1.0-alpha.5). Resolves the regression where
toggling a package on /stats/npm appended a fresh Plot SVG each time
without removing the previous one — coalesced renders between the pill
click and the URL-state sync meant dispatch-time cleanup only fired
once, leaving multiple charts in the DOM after each toggle.
