chore: import .claude command skills, CLAUDE.md, .gitignore, next_steps.md

- Vendor local .claude/ command skills (autopilot, plan, implement, etc.)
- Add CLAUDE.md pointing slash commands to .claude/commands/*/SKILL.md
- Untrack docs-Lokal/ and ignore .planning/ for local-only planning docs
- Include next_steps.md pulled from upstream
