Farvist v0.8.0 — AI kit + AI enablement

Two fronts for AI. (1) AI UI kit: chat thread + message bubbles + typing indicator (.chat/.message/.typing), a prompt composer (.prompt), agent-status dots (.status), and a full 'AI console' template (examples/ai-console.html). (2) AI-assistant enablement: llms.txt (llms.txt convention), llms-full.txt (paste-in context of every convention + component class), and ai-context.json (machine-readable catalog) — generated from the compiled CSS by 'npm run build:ai', served at farvist.com, and shipped in the npm package. 0 axe violations across the new template + docs in both themes.
