Add prefer-named-params rule

[create-inc-service-account]

Summary

• Flags functions with 2+ positional parameters, suggesting object destructuring instead
• Codifies CLAUDE.md: "Prefer to use named parameters (object destructuring) for functions"
• Skips callbacks (.map, .filter, .reduce, .sort, .then, etc.), React.forwardRef/memo, and functions already using destructured params
• Universal rule (not platform-specific)
• Severity: warning

Test plan
