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

+## [4.0.1] - 2025-10-07
+
+### 🎯 Intelligent Page Inference
+
+**IMPROVEMENT**: `--pages` parameter is now **optional** with smart inference from prompt or session context.
+
+**Changes**:
+- `--pages` parameter: Now optional, intelligently inferred from:
+  1. Explicit `--pages` if provided
+  2. `--prompt` text analysis (e.g., "blog with home, article pages" → ["home", "article"])
+  3. `--session` synthesis-specification.md extraction
+  4. Default: ["home"]
+
+**New Examples**:
+```bash
+# Simplest - pages inferred from prompt
+/workflow:design:auto --prompt "Modern blog with home, article and author pages"
+
+# Explicit override if needed
+/workflow:design:auto --prompt "SaaS app" --pages "dashboard,settings,billing"
+```
+
+**Commands Updated**:
+- `/workflow:design:auto`: All parameters now optional
+- `/workflow:design:ui-generate`: `--pages` optional with smart inference

 #### Changed
 
-**New Command Interface**:
+**New Command Interface** (v4.0.1):
 - **`/workflow:design:auto`**:
-  - Required: `--pages <list>`
-  - Optional: `--session <id>`, `--images <glob>`, `--prompt <desc>`, `--variants <count>`, `--use-agent`
-  - Defaults: `--variants 3`, `--images "design-refs/*"`
+  - All parameters optional with smart defaults

-    - Agent Mode: `/workflow:design:auto --prompt "Modern SaaS" --pages "home" --variants 3 --use-agent`
-    - Hybrid: `/workflow:design:auto --images "refs/*.png" --prompt "Linear.app style" --pages "tasks" --use-agent`

 - **`/workflow:design:style-extract`**:
-  - Required: At least one of `--images` or `--prompt`
-  - Optional: `--session <id>`, `--variants <count>`, `--use-agent`
-  - Supports: image-only, text-only, or hybrid inputs

 #### Usage Examples
 
 **Standalone Quick Prototyping**:
 ```bash
-# Pure text, agent exploration
-/workflow:design:auto --prompt "Modern minimalist blog, dark theme" --pages "home,article" --variants 3 --use-agent
+# Pure text with page inference (simplest)
+/workflow:design:auto --prompt "Modern minimalist blog with home, article and author pages, dark theme" --use-agent
 
-# Pure image, conventional mode
-/workflow:design:auto --images "refs/*.png" --pages "dashboard" --variants 2
+# Pure image with inferred pages
+/workflow:design:auto --images "refs/*.png" --variants 2
 
-# Hybrid input
-/workflow:design:auto --images "current-app.png" --prompt "Modernize with Linear.app style" --pages "tasks,settings" --use-agent
+# Hybrid input with explicit page override
+/workflow:design:auto --images "current-app.png" --prompt "Modernize to Linear.app style" --pages "tasks,settings" --use-agent
