Add component extraction trigger on 2nd page and audit duplicate detection

- Suggest workflow: Component Extraction Check prompts user to extract
  shared elements when starting the 2nd+ page in a scenario
- Dream workflow: Auto-extracts shared components and reports in summary
- Spec audit Level 3: Cross-Page Duplicate Detection compares sections
  across all pages, flags exact/near duplicates with severity levels
- Fix Freya role name (Scenario Architect → Facilitator)
- Remove duplicate trigger-map reference in Eira guide

+**Purpose:** Compare sections across all pages in the scenario and flag identical or near-identical content that should be shared components.
+
+**Process:**
+1. Collect all section definitions from completed page specs in the scenario
+2. Compare sections by structure (heading patterns, object types, layout)
+3. Flag matches:
+   - **Exact duplicate** — identical section structure and content across 2+ pages (e.g., navigation header, footer)
+   - **Near duplicate** — same structure with minor content differences (e.g., hero sections with different text but identical layout)
+   - **Repeated pattern** — same object types appearing in multiple pages (e.g., card grids, form fields)
+
+**Checklist:**
+- [ ] All completed pages in scenario scanned
+- [ ] Exact duplicates flagged with source pages listed
+- [ ] Near duplicates flagged with diff summary
+- [ ] Repeated patterns identified
+- [ ] Extraction recommendation for each finding (extract / leave as-is / parameterize)
+
+**Severity:**
+- **Critical** — Exact duplicate in 3+ pages (must extract)
+- **Warning** — Exact duplicate in 2 pages or near duplicate in 3+ (should extract)
+- **Suggestion** — Repeated pattern (consider extracting)

+### Component Extraction Check (2nd+ Page)
+
+**Trigger:** Automatically runs when starting the 2nd or later page in a scenario.
+
+**Purpose:** Identify repeating elements across pages and suggest extracting them as shared components before they multiply.
+
+**Dream mode behavior:**
+1. Scan completed page specs silently
+2. If shared elements found, auto-extract them as shared components (log decisions)
+3. Reference shared components in subsequent page specs instead of duplicating definitions
+4. Include extraction summary in the final review presentation
+
+**Key principle:** In Dream mode, extract automatically and report in the summary. The user reviews component decisions alongside page decisions.

+### Component Extraction Check (2nd+ Page)
+
+**Trigger:** Automatically runs when starting the 2nd or later page in a scenario.
+
+**Purpose:** Identify repeating elements across pages and suggest extracting them as shared components before they multiply.
+
+**Process:**
+
+1. **Scan completed page specs** in the current scenario's `pages/` folder
+2. **Identify common patterns** across completed pages:
+   - Navigation headers / footers
+   - Repeated form fields or input patterns
+   - Shared section layouts (e.g., hero, card grids)
+   - Identical UI elements (buttons, modals, alerts)
+3. **If shared elements found**, present briefly:
+   ```
+   I noticed these elements appear across your completed pages:
+   - [element] — used in [page 1], [page 2]
+   - [element] — used in [page 1], [page 2]
+
+   Want me to extract these as shared components now, or continue and handle it later?
+   [E] Extract now → routes to [M] Manage Design System
+   [L] Later — continue with page design
+   ```
+4. **If no shared elements found** (or this is only the 2nd page with minimal overlap), skip silently and continue to page design.
+
+**Key principle:** Don't block the design flow. This is a brief check, not a deep audit. The user can always choose [L] to defer.
