Directive for AI agents

All project context for Vojo lives in docs/ai/. Read it before making any non-trivial change.

This file exists only as a pointer. Do not add project knowledge here — put it in docs/ai/. Same rule for .cursorrules, .windsurfrules, AGENTS.md, .codex, home-directory memory, or any other agent-specific context file: if you're tempted to write project knowledge there, write it in docs/ai/ instead and keep those files as thin pointers.
