AI writer added to Reach template and form editors

Reach now includes an AI writer in the template and form editors. When you select any text element, a "Rewrite this..." section appears in the sidebar with one-click suggestions to shorten, lengthen, rewrite, or fix grammar. You can also choose a tone—Professional, Friendly, or Persuasive—or enter a custom prompt to describe exactly what you want changed. This gives you quick, contextual rewrites without the slower process of using chat mode, which regenerates your whole template.
