fix: Remove bash execution errors from demos using echo commands

Browse Source

**Critical fix for Image #1 issue:**

**Root cause:** VHS interprets typed text as actual bash commands in a real shell.
Text like "Create:", "Conclusion:", "12" caused "command not found" errors.

**Solution:** Wrap all narrative text in `echo '...'` commands for proper bash execution.

**Changes:**
- ppt-creator demo: All stages now use `echo` for display
- ui-designer demo: All steps now use `echo` for display
- File sizes increased (proper animation rendering):
  - ppt-creator: 496KB → 2.2MB
  - ui-designer: 262KB → 2.6MB

**Verification:**
✓ No "command not found" errors in VHS output
✓ Both GIFs render as valid 1400x800 GIF89a format
✓ All stage names and deliverables remain accurate per SKILL.md

**Technical details:**
- Before: `Type "# Stage 2: Storyline"` → bash error
- After: `Type "echo '# Stage 2: Storyline'"` → clean output

This fix ensures demos display workflow narratives without bash execution errors.
