docs: overhaul wiki with technical, vision, and testing documentation Move the technical documentation (architecture, Pivot IR, importers, CLI) from the main repo's docs/ folder into dedicated wiki pages under a Technical Documentation index, add a Testing page, and add a Vision section (product vision, planned SaaS API/CLI spec) clearly separated from what is actually implemented today. Add a categorized sidebar and correct Home's Features section to match the current implementation.
