Add Bonfire external plugin

[vieko]

Summary

Bonfire is a workflow plugin that maintains session context across AI coding sessions.

The problem: AI agents are stateless. Every conversation starts from zero—no memory of decisions, blockers, or where you left off.

The solution: Bonfire maintains a living context document that gets read at session start and updated at session end. Your AI partner picks up exactly where you left off.

Features

/bonfire:start	Read context, scaffold on first run
/bonfire:end	Update context, commit changes
/bonfire:spec <topic>	Create implementation specs (researches codebase, interviews user)
/bonfire:document <topic>	Document a codebase topic
/bonfire:review	Find blindspots, gaps, and quick wins
