- Why: - simplify first data checks for interview/demo audience - keep task reference in a stable docs location - What: - add short DBeaver connection section with ready-to-use params and quick SQL checks - update DE-task links in README to docs path - move DE-task from data/ to docs/ - Check: - README links resolve to docs/DE-task.md - git shows file move data/DE-task.md -> docs/DE-task.md
