fix: Correct ppt-creator demo errors and add ui-designer demo

**ppt-creator demo fixes:**
- Fixed incorrect stage grouping: "Stage 1-7" → accurate stages (2, 3, 4, 6, 7, 8)
- Corrected file descriptions:
  - refs.md: "speaker notes" → "citations & sources" ✓
  - notes.md: Now correctly shown as speaker notes ✓
- Added missing deliverable: notes.md (was omitted before)
- Removed incorrect sub-stage numbering (8b-8c, 8d, 8e)
- Added /output/ path prefix for all deliverables
- Increased height: 700 → 800 for better visibility
- File size: 295KB → 496KB (more comprehensive animation)

**Detailed error analysis:**
1. Line 21: "Stage 1-7: Content Preparation" was factually wrong
   - Stage 1: Structure Goals
   - Stage 2: Storyline (Pyramid Principle)
   - Stage 3: Outline & Slide Titles
   - Stage 4: Evidence & Charts
   - Stage 5: Layout & Accessibility (skipped in demo for brevity)
   - Stage 6: Speaker Notes
   - Stage 7: Self-Check & Scoring
   - Fixed by showing individual stages with accurate descriptions

2. Line 27: refs.md described as "speaker notes" - WRONG
   - Actual: refs.md = citations and data sources (SKILL.md line 37)
   - Actual: notes.md = speaker notes
   - Fixed by showing both files with correct descriptions

3. Missing /output/ path: All deliverables should show /output/ prefix
   - Fixed: All files now show as /output/slides.md, etc.

**ui-designer demo created:**
- 6-step workflow visualization
- Shows complete design system extraction process
- Accurate file paths and Task tool usage
- Demonstrates all key deliverables:
  - documents/designs/saas-dashboard_design_system.md
  - documents/ux-design/app_design_prompt_{timestamp}.md
  - React component implementations
- File size: 262KB

**Verification:**
✓ All stage numbers match SKILL.md workflow (lines 60-78)
✓ All deliverable filenames match SKILL.md line 33-38
✓ All ui-designer steps match SKILL.md lines 22-100
✓ Both demos tested and rendering correctly
