v0.1.1 - Bootstrap frontend rendering via Twig templates

Replace FSE block markup on the frontend with proper Bootstrap 5 HTML
rendered through Twig templates. The Site Editor remains functional for
admin editing while the public site outputs Bootstrap navbar, cards,
pagination, grid layout, and responsive components.

New PHP classes: TemplateController, ContextBuilder, NavWalker
New Twig templates: 20 files (base, pages, partials, components)
Enhanced TwigService with WordPress functions and globals
