More useful free tools and public navigation

The free tools hub is more complete. It now includes a LinkedIn Text Formatter for bold text, italics, bullets, numbered lists, cleaner line breaks, live preview, character count, and copy-ready LinkedIn post output.

Tool pages also have clearer categories, related tools, stronger create handoffs, and richer page metadata so it is easier to choose the right tool before generating a carousel.

Public pages now use a shared navigation and footer system with direct links to tools, docs, changelog, support, templates, and saved carousels where relevant, making resource pages easier to move through.
