fix: tighten review skill early-exit and add blind spots

[SimplyLiz]

Summary

• Tightens early-exit from score≥80 to score≥90 + zero warns + <100 lines + no new files (per-check caps hide warnings at 80)
• Adds "CKB's blind spots" section: logic errors, business logic, race conditions, incomplete refactoring, domain edge cases
• Expands Phase 2 checklist: race conditions, incomplete refactoring, secrets beyond CKB's 26 patterns
• Adds anti-patterns: trusting score≥80, skipping new files
• All three copies synced: ~/.claude/commands/ckb-review.md, .claude/commands/review.md, embedded constant in setup.go

Test plan

• go build ./cmd/ckb/... passes
• go test ./cmd/ckb/... passes
• Local skill, repo skill, and embedded constant are identical
