v3.55.0 — uiforge-detect (stack fingerprinting)

First piece of the archive→editable-source pipeline. uiforge-detect fingerprints a site's stack from the archive, offline, zero-dep — Next/Nuxt/SvelteKit/Astro/Remix/Gatsby/Angular/Vue/React-Vite/CRA/static, plus Tailwind-usage density, rendering mode, bundler, and sourcemap availability (the signal for whether Tier-A real-source recovery is viable). Verified: shadcn (Tailwind, no maps), vercel (Tailwind, 59/60 maps), linear (CSS-in-JS, 59/60 maps).
