New features

Arka Council. Multi-persona deliberation — Socrates, Elon, and Feynman answer the same question independently, then Arka synthesizes consensus, tension, and a verdict.
Quiz practice. Infinite quizzes on any topic with per-topic memory so questions never repeat.
Timezone conversion. arka convert 9am PDT to IST and natural-language date/time conversion; disambiguates from currency convert.
Open URL. arka open youtube opens sites in your default browser (distinct from play_youtube).
Interesting facts. Lightweight trivia without web search — tell me something interesting.
Self-improve loop. arka self improve analyzes the codebase and optionally applies fixes with --apply.
Operation modes. arka mode debug for routing traces; default agent mode keeps output clean.
Compose slides. Executive/pitch/academic style presets, action titles, validated pptx export with markdown fallback.
Frontend visual loop. Arka can now inspect its own frontend screenshots, judge polish, and retry a build command for up to N passes.
Domain agents. Astronomy, metallurgy, fact-check, science flow, Harvard ARK biomedical KG, repo context indexing.
Provider CLI. arka provider list/set/show/models with live OpenRouter autodetect.
CSV/TSV table previews over MCP. Clean structured previews for connected MCP clients.

LLM fallback skips vLLM unless explicitly configured; traces hidden unless debug mode.
OpenRouter credit errors fall back to Gemini/Groq when keys are present.
Self-improve and goal agent use clean user-facing output (no llm.txt dumps in normal mode).
CI fixed: clipboard routing in ai_only mode, ruff lint clean across src/ and tests/.

New guide pages for all features above; orphan guides (bookmarks, clipboard-history, docker-status, repo-health) added to navigation.
