[2.26.3] Design-iterator: auto-load skills, smaller iterations

- Added "Step 0: Discover and Load Design Skills (MANDATORY)"
- Discovers skills from all locations (plugin, global, project)
- Maps user context to relevant skills (Swiss → swiss-design, etc.)
- Changed iteration approach: ONE change per iteration, not 3-5
- Updated output format: focus on single most impactful change
- Added rule: "If you can't identify ONE clear improvement, stop"
