fix(robots): remove estático duplicado, corrige robots.ts e llms.txt

Remove `public/robots.txt` que era ignorado pelo Next.js em favor do
`src/app/robots.ts` (Metadata API). Adiciona `/signup` à lista de
rotas bloqueadas e remove referência ao `sitemap.xml` inexistente.

Restaura o link `/robots.txt` no `llms.txt`.
