The crawler subdirectory was the only active project. Moving it to the repo root simplifies paths and removes the unnecessary nesting. The vqa/ and immoweb/ directories were legacy/unused and have been removed. Updated .drone.yml, .gitignore, .claude/ docs, and skills to reflect the new flat structure.
