feat(html): browser renderer — runtime-cached tagged templates

Each template literal parses once, keyed by its strings array in a WeakMap: static parts become a <template> with hole markers, renders clone and fill. Interpolated values never pass through innerHTML (child values become text nodes or adopted DOM; attributes go through setAttribute). Event handlers set as properties so nanomorph copies them. Document-level roots (<body>/<head>/<html>) parse via DOMParser because <template> drops them. Replaces the v7 browserify transform entirely — production speed is now a runtime property. Tests run in happy-dom (new devDependency), including a check that server and browser renderers serialize identical markup.
