fix: update all stale Outside Voice references to include Gemini fallback chain

Updated Outside Voice description in Review Readiness Dashboard sections
across plan-eng-review, plan-ceo-review, ship, plan-design-review, and
design-review SKILL.md files to reflect the new fallback chain:
Codex → Gemini (gemini-3.1-pro-preview) → Claude subagent.

+Gemini 3.1 Pro has the strongest multimodal vision of any model. Use it as the **primary visual reviewer** — feed actual screenshots from Phase 1 and Phase 3 directly to Gemini for pixel-level design analysis. This catches issues that source-code-only reviewers miss: visual hierarchy balance, whitespace rhythm, color harmony, compositional weight, and AI slop patterns.

+
+VISUAL HIERARCHY & COMPOSITION:
+- Where does the eye land first? Is that intentional?
+- Is there clear primary > secondary > tertiary hierarchy?
+- White space rhythm: intentional or accidental gaps?
+- Squint test: does the layout hold when blurred?
+- Compositional weight: balanced or lopsided?
+
+COLOR & HARMONY:
+- Is the palette cohesive across all screenshots?
+- Contrast ratios: any text barely readable?
+- Semantic color usage: red=error, green=success consistent?
+- Dark mode: surfaces use elevation, not just inverted?
+
+TYPOGRAPHY AS RENDERED:
+- Type scale feels systematic or random?
+- Line lengths readable (45-75 chars)?
+- Font pairing: complementary or competing?
+- Heading hierarchy visually clear?
+
+SPACING & RHYTHM:
+- Grid alignment: everything snaps or drifts?
+- Consistent padding/margin rhythm?
+- Border-radius hierarchy or uniform bubbly?
+- Inner radius = outer radius - gap on nested elements?
+
+AI SLOP DETECTION (the 10 anti-patterns — visual check):
+1. Purple/violet gradient backgrounds?
+2. The 3-column feature grid with icon circles?
+3. Icons in colored circles as decoration?
+4. Centered everything?
+5. Uniform bubbly border-radius on all elements?
+6. Decorative blobs, floating circles, wavy dividers?
+7. Emoji as design elements?
+8. Colored left-border on cards?
+9. Generic hero copy ('Welcome to...', 'Unlock the power...')?
+10. Cookie-cutter section rhythm?

+2. One strong visual anchor present?
