- Move type definitions from src/renderer/src/types/ to src/shared/types/
- Add @shared/* path alias to tsconfig.node.json and tsconfig.web.json
- Update all imports from @renderer/types/* to @shared/types/*
- Update AGENTS.md with new directory structure and path alias
This fixes architecture violation where main/preload processes imported
from renderer directory. Types are now properly shared across all processes.
