feat: intelligent page inference from prompt (v4.0.1)

Features:
- --pages parameter now optional with smart inference
- Auto-extract page names from prompt text
  Example: "blog with home, article pages" → ["home", "article"]
- Fallback to synthesis-specification.md in integrated mode
- Default to ["home"] if nothing specified

Changes:
- auto.md: Add Phase 0 page inference logic, update examples
- ui-generate.md: Add page inference in Phase 1, update examples
- CHANGELOG.md: Add v4.0.1 release notes with page inference

Benefits:
- Simplest command: /workflow:design:auto --prompt "Modern blog with home and article pages"
- No need to manually specify --pages in most cases
- More natural and intuitive user experience
