chore: bootstrap pepa-pi-bot scaffold

Initial seed for an autonomous, self-extending Minecraft player powered by
Pi (pi.dev) and Mineflayer.

Includes README, AGENTS.md mandate, .env.example, MIT LICENSE, package.json
with mineflayer + dotenv, and empty skills/ extensions/ prompts/ dirs for
the agent to grow into.
