pos ai gemini: --session gives ask/chat persistent memory (~/.local/share/linux_post_install/ai/<name>.json, capped 40 turns), new 'sessions' subcommand to list/clear; --system injects a Gemini systemInstruction on every turn without storing it in the session file. Telegram listener keeps one session per chat (telegram-<chat_id>), clears on 'ai /reset', passes a Telegram-voice system prompt (emojis welcome), and strips markdown from replies before sendMessage since messages are sent as plain text.
