Second Brain v0.1.0

First public release of Second Brain — a local-first, open-source second brain for your desktop.

Highlights

• Memory you own: everything stored as Markdown in your private GitHub repo — synced both ways in real time.
• Tiered memory + sleep cycles: short/medium/long-term memory and a nightly 5-question learning review.
• Specialist agents: chat with Warren Buffett, Bill Gates, Elon Musk, Naval, Jobs — or build your own. Multi-agent Meetings turn debates into action items.
• Today dashboard: daily intentions, tasks, quick notes.
• Natural-language automations: "every day at 8am summarize my whatsapp" → scheduled cron.
• Local AI: bundled llama.cpp + GGUF models — fully offline. Also Codex/ChatGPT sign-in, Claude token, OpenAI, Gemini, Grok, Ollama.
• Local RAG: semantic memory search via local embeddings.
• Connectors: WhatsApp (QR), Telegram, Postgres (read-only), custom MCP servers.
• Auto-updates: the app checks this repo's releases and updates itself.
