feat: Add Sequential Thinking to Code Review + Frontend Validation

Enhanced code review and frontend validation with intelligent triggers: Code Review Agent Enhancement: - Added Sequential Thinking MCP integration for complex issues - Triggers on 2+ rejections or 3+ critical issues - New escalation format with root cause analysis - Comprehensive solution strategies with trade-off evaluation - Educational feedback to break rejection cycles - Files: .claude/agents/code-review.md (+308 lines) - Docs: CODE_REVIEW_ST_ENHANCEMENT.md, CODE_REVIEW_ST_TESTING.md Frontend Design Skill Enhancement: - Automatic invocation for ANY UI change - Comprehensive validation checklist (200+ checkpoints) - 8 validation categories (visual, interactive, responsive, a11y, etc.) - 3 validation levels (quick, standard, comprehensive) - Integration with code review workflow - Files: .claude/skills/frontend-design/SKILL.md (+120 lines) - Docs: UI_VALIDATION_CHECKLIST.md (462 lines), AUTOMATIC_VALIDATION_ENHANCEMENT.md (587 lines) Settings Optimization: - Repaired .claude/settings.local.json (fixed m365 pattern) - Reduced permissions from 49 to 33 (33% reduction) - Removed duplicates, sorted alphabetically - Created SETTINGS_PERMISSIONS.md documentation Checkpoint Command Enhancement: - Dual checkpoint system (git + database) - Saves session context to API for cross-machine recall - Includes git metadata in database context - Files: .claude/commands/checkpoint.md (+139 lines) Decision Rationale: - Sequential Thinking MCP breaks rejection cycles by identifying root causes - Automatic frontend validation catches UI issues before code review - Dual checkpoints enable complete project memory across machines - Settings optimization improves maintainability Total: 1,200+ lines of documentation and enhancements Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

+## Validation Workflow
+
+### Quick Validation (Simple Changes)
+
+For minor changes like color updates or spacing tweaks:
+
+1. Visual check at 1-2 breakpoints
+2. Verify hover/focus states
+3. Quick accessibility scan
+4. Report: [OK] or [WARNING]
+
+**Time:** 1-2 minutes
+
+### Standard Validation (Component Changes)
+
+For component modifications or feature additions:
+
+1. Visual check at all breakpoints
+2. Test all interactive states
+3. Keyboard navigation test
+4. Basic performance check
+5. Report: [OK], [WARNING], or [ERROR]
+
+**Time:** 3-5 minutes
+
+### Comprehensive Validation (New Features)
+
+For new components or major refactors:
+
+1. Complete visual review (all categories above)
+2. Full interaction testing
+3. Cross-browser testing
+4. Accessibility audit
+5. Performance profiling
+6. Report: Detailed findings with fixes
+
+**Time:** 10-15 minutes
