Agent-driven Contexto installation without leaving the chat interface

[sm86]

Problem

Installing Contexto currently requires users to leave their chat interface (Telegram, Discord, etc.), get access to a machine, and complete the setup from the CLI. This is a significant barrier — it breaks the conversational flow, requires technical access most users don't have, and creates multiple points of drop-off.

Proposal

An agent (e.g. a Telegram or Discord bot) should be able to complete the entire Contexto installation without the user ever leaving the chat. No machine access or CLI required. The agent should handle:

1. Initiation — User asks the bot to install/set up Contexto
2. Authentication — Any required auth is handled inline via deep links or in-chat prompts
3. Configuration — The agent walks through config options conversationally

Installation completes when Contexto is configured. Verification that it's working correctly is handled by a separate module (see linked issue).

Why this matters

• Eliminates the need for machine access and CLI — opens up Contexto to all users
• Reduces drop-off during onboarding — leaving chat to find a terminal is where most users give up
• Keeps users in the interface they're already comfortable with

Acceptance criteria

• Agent can complete full Contexto installation via chat (no machine access or CLI needed)
• Works for at least Telegram and Discord bot interfaces
• Errors during installation are surfaced clearly in-chat with recovery suggestions
