v0.4.0

Added

• Per-tool AI skills now ship in scaffolds: full SKILL.md (and reference) trees under .claude/skills/ and .cursor/skills/ for both starter_workspace and minimal_workspace, exposing toolkit workflows (e.g. rest-api-pipeline-workflow, data-quality-workflow, dlthub-platform-workflow, transformations-workflow) and per-step skills (create-*, add-*, adjust-*, debug-*, deploy-*, explore-data, build-notebook, init-dlthub-workspace, ...) directly to Claude Code and Cursor. scripts/generate_ai.py was extended to materialize them.
• CI lock-check job that runs uv lock --check to fail PRs when uv.lock drifts from pyproject.toml.

Changed

• Refreshed onboarding guidance for dlt show run and MotherDuck credentials.

Fixed

• MotherDuck credentials handling in scaffolded workspaces.
